Yes, they are the black version of the RD2s and that is a decent price. If you have an LBS that deals with fixed bikes, I'd reccommend talking to them about it. Chances are, you'll be able to get most of the stuff you need for about the same prices that you'll find them on the internet. If it's not out of your price range, definitely get the wheels built at a good local shop.
