I ordered my Open Pro rims from Harris and got the usual competitive pricing, great customer service and lightning fast shipping/delivery.
I use the Spin Doctor (~$40) truing stand and and Park Tool TM-1 tension meter (~$55). If I can build true and properly tensioned wheels, anybody can. It's a great experience.
Sheldon's article on wheelbuilding is great, and I also found the $9.00 e-book
Wheelbuilding to be extremely helpful.
