If you buy from an individual on eBay, it's always a gamble as to what you get. Do your homework on the seller before buying. Some members here sell there. There are authorized dealers selling there. Ask for more pictures, make sure they'll accept a return. If it turns out to be a fake or misrepresented, you'll get your money back, but it will be tied up for a while. The process on returns/refunds on eBay is a pain in the ass.
IMO, buying from an individual is so much easier here. A quick check on someone's profile will reveal who your dealing with. Just looking at Post History will let you know if someone here is a flipper or is involved in the community.
