I found a scratch and dent for $279 with the wan slot, no card. They don't come with the WWAN wiring for the antenna, so you'll need to order that part (X055J), costs about $30. the kit comes with a new LCD back panel. So my scratches were on the LCD back Panel. Card was also on the outlet, Dell 5530 (ericsson), cost $170. So one could be put together for less than $500. I've seen references to promotions for getting a rebate from AT&T with a 2 year contract. the costs for the Mini 9 then drops to $99. But at a 60$/month fee for the service is a little steep unless you can get discount pricing from AT&T through your business.
