i just got my new gaastra g-spot 15.5 at
for a very reasonable price. actually, it was the best offer i could get.
BigBoySport.de has most of the kite brands, if you want to know details, check the web site or call michael at the shop
just for you to know, i have no further relationship with this shop, but got the link in the kitesurfing-kiel forum.
hope this helps
