Found a 2009 Windsor Knight on Craigslist for 600 or B/O. It is barely used and includes a Cateye computer? This seems like a good deal for a full Ultegra bike. I searched the forums but could not find a lot of info on this bike. Is this a good first bike? Is say $550 a good deal for this bike?

Also, it is a 60cm bike. I am just a hair under 6'1" with a 34.5 - 35 inch inseam depending on how hard I push up while measuring. Would a 60cm bike be too big?
