Yes this is a scam, I've actually have reported these listings to ebay before, because they always use the same phrase about the emailing for terms of sale part. In fact I have emailed them before, and the ask you to send them the money through western union, which is in direct violation of Ebay's terms. A lot of times, you think you can trust these because the seller has great feedback, but the accounts are usually hijacked, and the scammer ends up fooling a few buyers until ebay catches it. It is sad really, that you would think someone is selling that camera at that kind of price, it is just not possible.
