In reply to stevev:
Yep, a great set of links.
No 1. Trade only exhibition.
No 2. Climbing wall manufacturer.
No 3. A climbing forum (possibly useful if you can read and write German).
No 4. Probably three of the worst and most expensive online shops in Germany.
You will find the next decent sized town is Lindau, 27km down the coast. There are loads of outdoor shops there.
Lindau is in the Allgau region and you can click on this link and then check each of the over 50 outdoor/mountaineering shops listed here.

Or go down the climbing wall and ask!
