One more plug for Ben's. I've purchased a few different Carradice items from them in the past. Just a few weeks ago I ordered a Nitto M-12 rack from them and then freaked out thinking it would not work with the V-brakes I have on the bike (Nitto specifies that they are for canti brakes). I exchanged emails with a gentleman in the shop named Drew who took the time to look at some pics of my fork and determined that it "should work" - and it did.
My first choice is always my favorite LBS, followed by RBW - - but there are times when they just don't have what I'm looking for.
