a good starter frame is the IRO mark V. decently cheap, generally around 180, and it's steel, but it has teardrop shaped tubing so it is more rigid than a standard round tubed steel frame, but not quite as rigid as aluminum. and they're tough as hell, plus they come with a good warranty in which if the frame become unrideable for any reason, IRO will replace it at half price for you. it has better welds than the bareknuckle, looks and rides better than the langster, and is infinitely more reliable than the brassknuckle. back in boston (US), they were by far the most popular basic frame around, and they're good enough that when people got really into the whole fixed thing, they'd keep the frame and just upgrade their parts. i've got one and it's simply a fun bike to ride. iro's site... good luck with your decision.
