+1 on the jobst book and the Open Sport rims.I built my wheels for the first time with those rims,Sansin($12 pair on e-bay-perfect condition) hubs and help from That book as well as the SheldonBrown site and the Zinn book.(Zinn and the art of road bike maintenance)I built my wheels myself cause the choice of new ones with 126mm spacing were limited and I don't trust or wish to pay any lbs mechanic!The wheels are a great source of pride as they came out splendidly.I recommend you practice truing on old disposable rims first!
