I'm a novice and I'm looking at buying a used Beamer TSR 3.6 for cheap, but now I'm wondering if I'll be crawling into a bag of wilted lettuce. I don't have enough experience to tell a crisp one from a soggy one, but I will look for frayed edges and stressed stitching. One last reason to doubt the wisdom of the pruchase: the seller used it as a trainer at his kite school. What say - bad choice or worth a try for a first snow kite?
