It is just a different camera. I am not a pro - though for some reason I find myself in circumstances that one might find a professional working... anyway, I understand your dilemma, and I am happy to provide my opinion.
Honestly, in the $ range you have budgeted, either a Panasonic or Sony or Canon miniDV based camera would provide you with great quality video. I also think a hard-drive based camera doing standard definition would do quite well for you, too. Based on my previous experience working with a disc from a MiniDVD camera, I just can't bring myself to recommend that format because the image quality is not good. They may be convenient, but at the expense of poor quality... well, they aren't THAT convenient in my book.
There are other things to consider - some may be important to you, and some may not be. That is where you need to make a decision.
1) Does the camera have the ability to add a 2x (or greater) lens? If you are shooting baseball games, closeups would be REALLY cool - and the 10x-12x zoom just isn't enough. Be sure to turn OFF optical zoom. Very bad. The tele- lens usually screws on. The manufacturer's web sites typically list what accessories will go with the camera you select.
2) If you decide a hard drive camcorder is the way to go, how will you archive the video? Not all the video you shoot will make it to the DVD that you share with family and friends. But there *may* be video in there you want to keep - even if you don't share it. In my case, I have been finding that for every hour of tape I shoot, I end up using around 8 minutes. The exception to this is when I am shooting bands (bar, concert, whatever...). But the stuff that is cut can be useful in other projects... When I fill a miniDV tape, I pop it out, lock it, label it and pop in another one. Whe I get home, I connect the camera to my computer, transfer the video and put the locked tape in a box. I edit - and if I accidentally cut and delete something or if I want a particular sequence from 6 months ago, I just go back to the marked tape and re-import it. If I use a hard drive based camcorder, when I transfer that video to the computer, and delete it from the camcorder's hard drive (so I can shoot more video), I need to somehow archive that video in the computer. If I don't archive that video in the computer and start editing, all the stuff that is cut and deleted will be gone forever.
3) Check to see if the camcorder has an external mic jack. When I first started shooting video, I thought the built-in mics were just fine. I learned that external mics provide so much more clarity and audio pick-up... it can be an inexpensive way to make your productions more "pro-like" because they sound so much better. Plus, when you add an external mic, you certainly LOOK like you know what you are doing! Sony is interesting this way. Many of their cameras do not have an external mic jack, but they do have a proprietary hot shoe that allows use of proprietary Sony external mics...
4) The chip differences (3 CCDs vs 1 CCD vs 1 CMOS) end up being an activity where "size matters". The whole point of the chips is to digitize what the lens sees and move that digital image to the tape (or hard drive). For normal people like me - and probably you, three tiny CCDs with the same surface area as 1 big CCD or 1 big CMOS chip should yield relatively similar results (I know, someone is likely to yell at me here - this is MY opinion, only). That said, the Panasonic cameras have made quite a name for themselves because of their 3CCD array. Frankly, I have been seriously considering getting one just for low-light situations because my camera does not do too well in low light...
5) It is all about how YOU handle the camera. I am certain that a professional videographer with a $200 camera will yield better results than a nervous amatuer using a $2000 camera. Be sure to take time to get to know your camera. Use a tripod. Get that external mic. Get a high-capacity battery or two. Don't zoom - but if you must, zoom SLOWLY. Pan slowly. Pay attention to what you see on TV. Keep that in the back of your mind when you are shooting. The folks who staff cameras for a living can teach us a lot. That does not mean they tell us what they are doing - we can SEE what they are doing - we just need to pay attention. We don't need to get paid $ for it, but we do want to capture good video...
6) If you decide to get a hard drive based camcorder, be almost religious about transferring your video off the camcorder to your computer. The last thing you want is to have not transferred video and want to grab new footage - only to find out that you are running out of hard drive space. With a miniDV based camera, the tapes are cheap. ~$3 each. I get them in 8-packs. Each tape holds an hour (at best quality - SP).
7) Take a look at http://www.camcorderinfo.com/ratings.php . Any of them in the top 10 or 11, reviewed in 2006 (but none of the DVD or miniDVD based camcorders), would probably easily meet - perhaps exceed - your image quality requirements... but it is the "other stuff" (listed above) that *could* be the difference between, "Let's hide, Russ wants to show home movies again" to "Russ, could you play that DVD again and shoot more video for us?" Of course, your video editing skills and the subject will have an impact on that too...
I realize I didn't select a camera. Using all of the above criteria, in my opinion, that your short list should include the Panasonic PV-GS300, Panasonic PV-GS500, Sony DCR-HC96, Sony DCR-SR100... Any of them will do a great job for you. If you get a MiniDV tape based camcorder that uses FireWire to transfer video, you will need to get the FireWire cable, too - for some stupid reason, the manufacturers don't include those in the box. 4-pin to camera; 6-pin to computer... which reminds me: Your computer needs to have a FireWire port... and you need a pretty good sized hard drive with lots of available space. The USB cable included in the box with the camera will transfer only things on the memory card (like stills).
I hope this helps.
