Hate to sound like an old geezer with the old sayings, but often they get to be old sayings because they are true.
"If it seems to good to be true, it probably is"
"There's no such thing as a free lunch"
If you are looking for a good deal, think about how someone could offer such a good deal? In this case, the price is less than wholesale, I'd say less than the cost of its manufacture. Then you have to ask yourself whether the seller somehow got the goods at a really great price (which might be possible if the market is flooded and people are trying to dump the merchandise, but this was for brand new just released machines with state of the art components that are in short supply) or if they are just being really nice and doing everyone a favor (highly unlikely on EBay, and besides why wouldn't they just donate them to a school or charity?). As noted, neither are likely. Scammers exist because people are greedy and looking for deals they know can't exist. They are looking to get something for nothing, just like the scammer. They just hope that somehow this time the dream will come true. It never does.
