The videos look fine. Here's why. You met the first goal of any good, great picture or video and that is "The subject matter or content."
I've seen too many get caught up in the hardware trap and miss out on the content, subject matter.
I wouldn't change a thing.
I take video of adoptable cats at my local humane society and upload them to youtube and petfinder. Up until now, I've just been using the movie feature of my Canon Powershot A590. While it's okay for what I'm using it for, the video can be shaky and the mic picks up a lot of squeaks when I move the camera around. (I can make up for the noise by replacing the sound with music on youtube.)
I've been looking at a couple of inexpensive flash camcorders. Specifically, DXG-595V, Sony Webbie MHS-CM1, Samsung SC-MX20, and the seemingly endless supply of flip cameras. I'd like to remain below $200 or as close to it as possible.
Would purchasing any of these camcorders make much difference in the quality of my videos? Would you consider the purchase worthwhile for what I am using it for?

Thank you in advance for your advise!
