Buying a new camera for my Youtube videos!

Hello everybody this is 2cool4games. I am thinking that my 480 PI is kind of the old quality, I think now is the time to get a new camera because all the cameras in Bestbuy or any kind of Super shop has cameras that are at least 720 Pixels. I think I am going to buy one of the flip cameras with my own hard earned cash from working on the house for hours, It's like sweat on my money if I earned of painting our house and scraping and priming. Very tiring because you have to get prepared.
