These guys have a pretty solid reputation around here. I have one of their very early ebony sets when they were California based and it was a steal off Ebay. Actually though I think only the name is the same. Anyway, I don't think they are brick and mortar, but they do have a UK phone #.

Can anyone recommend a decent chess set within £400 please?
Staunton with heavy pieces, what are you using guys?
