Hi guys. I ordered a Phantom 2 Vision + V3.0 on ebay last week from Coptershop.com. It arrived today, but it was the V2.0. I contacted them and they offered me 2 choices, which I think was great of them. The first option was to refund me $250 of the cost and keep the V2.0. The other was to ship the V2.0 back and they'd ship me a V3.0. Is the V3.0 worth $250 more than the V2.0? What would you guys recommend I do?
