There are plenty of choices for "beaterish" frames. My first choice is 5-800 cf frames, as I have not seen any track cf frames other than the Look frame. i doubt we could get a group buy on that one. My second choice would be a ti frame. If I wanted a cheapish alu or steel frame, others have mentioned the sources.

Also, a fork would be nice, along with one water bottle boss. I would prefer fender mounts, but I doubt that would be a group consensus.

Also, I think a 1 in headtube would be a great idea, as it would solve the threaded/threadless debate, at least a little bit.
