Check out jensonUSA they had the Saint RD on clearance for like 25 or 30 bucks yesterday, requires the use of a Saint (or one of their other compatible model) hub to mount to as it doesn't use a traditional hanger but mounts to the axle itself, just something to look at if you are wanting to build right now and save quite a few bucks on at least that component. Good luck and have fun, everything I've heard about the Saint claims it's tough as nails.
