As long as the frame fits you well, the Co-Motion S&S frame with all the extras sounds like a really good deal for about $1,500 (half price over new.) Is the frame in excellent condition? You will be hard-pressed to find a similar deal plus all the stars gotta realign to give you the right specs. Obviously, you will need to stretch the wallet to build it complete. If you're not in a rush, it can be a great winter project and have it fully built by the spring. The S&S frame/case should make this bike really enjoyable on overseas trips (if that's also something you want to do.)
