You can try out the British shop of Brain Sharp. That's where I got my Pendlay bar from
all the other stuff can be bought in Germany itself, although you never pay the same as in the States.
for instance: http://www.nerlinger.com/
(in German and WFS)
you can also try http://www.fitness-seller.nl/
WFS (there I purchased a KB set and some bumpers. Didn't recieve them yet so I can't give any pointers of those products. They ship to whole Europe.)
