Cnettles11 isn't lying... the kit base IS YOUR FRIEND!!! It's not like some idiot threw some metal parts together and called it a frame. An actual engineer designed those parts to be a solid drivebase for anyone to use. Plenty of great teams still use the kit frame. If you look team 148's designs on frc-designs.com, you can see that their basic sheet metal frame bears a striking resemblance to the old IFI kit frame.
If you're still not convinced, I'd like you to watch this video:
