Hey guys, I want to buy a cabrinha drifter from ebay because it's too cheap, just $800. But I don't know if it is safe. http://www.ebay.com/itm/NEW-2012-Cabrinha-Drifter-11M-C1-Kiteboarding-bar-lines-leash-pump-bag-/321221626037?pt=LH_DefaultDomain_0&hash=item4aca4d08b5 So, what do you think? Thanks..
