You're better off buying from eBay, Adorama, or B&H than KEH. Both Adorama and B&H have professionals who monitor this site and photo.net and try and work out any problem, even if it happened weeks ago. Ebay now has a 100% buyer satisfaction policy that guarantees your purchase price plus shipping back. KEH doesn't fully test their items and as such, you'll go to use some feature and it won't work. Happened to me many times. I'd much rather buy from an individual that knows his gear than the KEH appearance-graded items.
