How much can I sell a new G1 (Google phone) for on eBay?

I've got an extra HTC G1 (Android) phone that I"d like to sell. How much can I get for it? I'll probably shave a few bucks off the going price so I can just do it quickly.|||I've seen new ones going for a minimum of $400.That was a couple of months ago, so check recent auctions to compare.|||Look under the completed auctions for the G1 on ebay and see what prices they have been selling (and not selling) for.|||HOLITA HELLO
