I've started building my build kit ... using the JensonUSA site, as they have customizable build kits that you can tweak, save, and print. Prices aren't too bad, but that is secondary right now.
My present kit contains many of the parts mentioned before in this thread: Avid BB7 disc brakes, SRAM X.9 RD & FD, SRAM X.0 twistshifter, SRAM PG950 11-26 cassette - didn't go with 11-32/34 because I'm leaning toward a MTB crankset of 44/32/22. Don't need a 32t in the back when I have a 22t in the front.
I already own stems, handlebars, saddles. Will probably go for a carbon seat post, more for vibration damping than weight savings.
Haven't decided on the crankset yet. It doesn't have to be a high end crank, I won't be pushing it that hard. Considering the new Shimano LX or going with any year of XT. There are also FSA options and Jenson has some Race Face's on closeouts. I've seen a lot of positive reviews of both the Race Faces and FSA cranks, but the safe choice seems to be Shimano.
Biggest area of indecision is the wheelset. I'm not hard on wheels. In fact, I've never had a wheel repair of any kind, not even a truing. My '87 Bridgestone still has the original wheels, spokes, etc., and has never be trued (and it is true). OTOH, I don't want to get something like a Gunnar and then put on crap wheels.
So I'm looking for advice on 26" wheelsets, and am open to suggestions on the cranksets too. I could follow the example of the Salsa Ala Carte and go with 32h XT wheels. For example, these:

Or better yet, these:

Or lighter weight, 24 spoke wheels like these:

Of all of these, I guess I'm leaning toward the XT/Mavic 717 set.
