So now that I have mine on hand, I figure I should share the info.

I got my XX1 groupset with GXP crankset, no front chainring or bottom bracket for $949 shipped.  Also got XT brakes with 180 adapter for front and side to post mount for the rear for $95 each end.
Also got Thunder Burts and Rocket Ron for $54 each.

These all came from Planet Cyclery.  They are in Colorado, used to be San Diego, delivry was free and showed up in 2 days.

They are worth checking out.

I got my XX1 used on craigslist. 150mi like new complete with 4! XX1 chainrings, 2 XX1 chains, 4 masterlinks and new cable housing for $650 shipped to my doorstep by a bike mechanic. Deals are out there if you are patient and the seller is willing to ship
