Any Good Video Capture Programs?

The subject says it all, I'm looking for a, preferably free(if not very cheap) video capture program that produces good framerates and quality, while not affecting the in-game framerate much.
I currently use Frapps and like it but the 30 second time cap is annoying and i'm not paying $37USD for ONE program. If it was $20 Canadian or less i would but $37USD is too much, thats $45 Canadian, for that price i should just get a capture card and do it the ghetto way.
