I'll fifth or sixth the praise for Dan's Comp. I've bought the spokes for 4-5 wheelsets over the years. Never any trouble, always cut to the mm, and properly threaded. Usually a day or two turnaround, at great prices. (I've only used the cheap Sapim double butted spokes in silver, and brass nipples.). They specialize in BMX, but stock spoke blanks suitable for 700c wheels. You do have to call, but they've always been helpful and efficient.
