Canon Elura 100, I got mine for about $350. The image quality is the best in that price range.
Actually, if all you're going to do is upload to YouTube, you would be fine with any cheapy, even one from a yard sale or whatever as the previous poster said. The image is reduced so much on YouTube that you can't tell the difference. Just make sure it's MiniDV or Digital8 and has a firewire port (and make sure your computer has a firewire port...)
