Well Suze, you can't condemn all of ebay just for that. They do have alot of useful stuff and I usually have good experiences. But as anything else where counterfeitting comes into play, it's Caveat Emptor. Obviously if the authorized retailers are putting customers on a waiting list, and some unknown person out of nowhere claims to HAVE something that everyone wants, then you should definitely be suspicious. Like I've stated before, fakes are getting frighteningly real. Articles are being published now that say even the experts are having trouble telling them apart.
A faked receipt just adds another element to the deception.
I say get it from an authorized retailer at this point. It's too big of a risk and too much money to play with.
