Probably will get you up and running for a good price, if you want Aluminum for the frame material and that Style of frame is what you are looking for. Not sure about the quality of the componentry at that price level. You will probably upgrade what you don't like soon enough, and keep what works. Fixed gear riding seems to be a constant changing of components for whatever reason. Part of the fun, I guess.
