Briarmill has something similar. Designs like that work fine at home, but are risky in a crowded bar; they will support an instrument with no problem, but can easily be elbowed off the table or shelf by the usual clumsy drunk. The "pub prop" is the most secure solution I've found, as it clamps onto a shelf or tabletop and can't accidentally be knocked off.

So far as I know, the address is still ok; a friend bought one a few weeks back with no problems. He's probably just behind on answering mail (one-man operation) but if you get no response soon I'll see if I can get him on the phone. Keep us posted.
