I just bought an a4000 here in Canada (where the OP is selling from) With a revision D motherboard 040 in great cosmetic condition on ebay for $600 so ya I would say his asking price is more than twice as much as it should be. He is obviously just looking at the other crazy priced listings and going by that. None of those a4000s are selling either they just keep getting relisted. I wouldn't even pay that much for an A4000T
