Well, when it was time for me to replace and upgrade my 36" Phillips tube TV, I did alot of research on the technologies out there at the time, it was a year ago, and then took myself to the stores.
I went to CircuitCity, BestBuy, CompUSA, PC Richards, and even Sears, not so much to do a price comparison, which came in very handy in the end, but to take a look at the images and compare the regular tube TV (CRT), Plasmas, LCDs and DLPs (standard vs LED).
What I discovered in my search was that the "standard" DLP gave me the finest, most "natural" image without any "little blocks" which could be visable up close to the unit.
One of the reasons I didn't choose the LCD nor plasmas was that they still showed the little square in the image up close, where as the DLP didn't.
I ended up choosing the Samsung WideScreen HDTV DLP without the LED, I found it to give the best image overall and the most "natural" image.
Even my friends who have Plamas and LCD TV's come over and are dumbfounded by the image's fluidity, no breakup, nor pixelation.
I have to also state that I ended up switching from Satellite TV receiption (Direct TV) to HDTV Cable reception, for it gave me a better image than Satellite. That's something to also consider, that you must get the HD service from your cable provider, otherwise it won't matter what tv you get it will still look sub-par.

This is a pretty cool place to start.
PS, I have not regretted my choice, for the price, features and image/sound and options, I am extremely happy with the Standard, and can't consider being locked into a "fixed" number of pixels on the screen as I had been on a CRT, which is what you end up getting in an LED DLP/LCD/Plasma after all, but not with the Standard, for there are no pixels to see, just a fluid like image! Flawless.
