When I buy expensive electronic devices, I try to buy second hand ones. I got my N900 from Amazon (Warehouse Deals, which belongs to Amazon) for 310 bucks. The new one was 420 bucks or so (at that time). The phone needed a reflash (had the contacts and stuff of the previous user). The phone was in very good shape, just like new. Now you can find a second hand one for about the same price, on Amazon.
