Retro Sounds and Loops

I've got a lot of animations in the works at the moment, some are far from finished, some are just waiting on sound. One thing I have found with making videos is the sound makes it, if your sound is off it can make a great video mediocre. That's why it would be great to have some nice sound gear, guitarcenter.com has kaossilator gear and I think it would be awesome for the kind of retro sounds I'm after for my animations.
