Hi Sharon,
Yes, theres a link from that site to TAMCO and I imagine that its much the same as Mandolin Bros. but a great deal smaller. I go to Mand. Bros. regularly but only through their web site. Its on my list of places to visit if I ever get as far as NY. If you're ever in London, you can get a train down to Brighton but I'd give Trevor, the owner, a call first to make sure he'll be there. He hangs out on the Mandolin Cafe. I don't think you'll find any Holoubeks so far as I know apart from mine, he's only ever had one other in stock.

The main distribution for them in the states seems to be a chain which goes under the name "Gallery of Strings"
