Stephen, I was talking about a full on TT helmet like the ones in the picture above. They make a huge difference. Whether you get a frame and build it up or buy something used off ebay (or whatever) I would suggest you stick with Ultegra level components. It's the best compromise between cost and performance (IMHO) I would also suggest 10sp as 9sp stuff is becoming harder to find. If you find a complete bike with 9sp, that's ok.
