What's a good camera used for YouTube?

I film random stuff here and there. I currently have a Canon PowerShot A490 which is okay for pictures but terrible for videos. The quality is crap. I'm looking more into creating videos and skits to upload to my YouTube channel. My budget is 100$, I wanted to know if there are any decent cameras around that price. I was about to get a Flip since it's around 60$ for 4GB but the quality isn't that great to me. If there are any other cameras that has good resolution, and is around 100$, please let me know. Thanks!
