BF charges $55 to build a wheel plus the prices of components and shipping. Danscomp.com is a better place to build custom wheels because to build a wheel and shipping will be free if you pay for parts.

My personal choices to order a custom wheelset with DT swiss 350 hubs or buy one from China. I bought a set from China with Novates D041SB/D042SB hubs which are almost as good as DW Swiss ones. Can't beat a $142 set with a nice sealed bearings hubs, double wall rims, and 32 spokes wheels.
