G4 needs a new hard-drive..which one?

Hi there, new to the forums so please forgive my noobiness =s

Does the new hard drive need to be specifically for an ibook G4 ? or do i have other options? trying to do this on the cheap as the laptop is hardly worth anything these days (but i love my ibook lol).

Any advice would be much appreciated

Any brand will do. I'd check out Newegg. They're great.
