+1 for Merlin. They didn't build my wheels, as I bought factory MT65s from them, but they were great and re-jigged everything on the bike too (gears, brakes, even put the tyres on) for an extra £10 while I waited.
I've always popped into the shop … really friendly and informative on the three times I've been in recently … they even gave me sweets last time, but that might have been because they had forgotten to post my order 🙄
Know a few people who've had wheels built there and they've only got good things to say about them.
BTW, looked at Wheelpro site last night when reading another thread … the tone on the website alone would put me off personally, although it sounds like the wheels they sell are pretty good when they can get them.
