Hong Kong listing, it is very unlikely to actually be new, it will probably be a used n900, and not complete with all cables or crappy quality substitute cable. There was a post here about the Ebay listings for n900 made in Finland brand new from Hong Kong lister with great ebay rating and volume sales, it turned out to be missing cables and actually still had another persons information on it.

Your much better looking for used auctions, with people with sales less than 1000 and 100% ratings, these are likely to be regular owners of n900, also you want a listing that shows actual images of the phone that is for sale, not stock photos, so you can judge it's condition.
