everything prooftheory said is spot on. If you go to Bikesdirect there are a couple of cheaper models around $300 that might be acceptable to start with. But I would highly recommend getting something with two brakes and a flip flop hub to start on that way if fixed isn't your thing you can still ride it single speed with the freewheel. I made the mistake of buying a cheap fixie for my first one that cost about $200. I put at least another $100 in parts into it in the first year to make it ride able and not long after that I was ready to upgrade. Wish I came here first and got advice and then got a Kilo TT because I would probably still be riding that if I did
