It's the one in this listing:
http://www.amazon.com/MID_M729-Android-Cortex-1-2Ghz-Camera/dp/B009PIQFHA.
The one that I have is in pretty nice condition; aside from one or two scratches on the front, it works perfectly (and it's factory reset, so no software installed).
It includes the tablet (obviously), the charging cable, and two USB cables (one for transferring files to a computer and one for attaching a 3G dongle or any other USB device).
I'm asking 0.14 BTC for it (~$50 right now), which includes shipping to the USA with USPS priority mail. This price will change if the price of Bitcoin goes up or down.
My terms are as follows:
1. I will provide a picture of the device powered on upon mailing (as I'm inserting it into the box). You accept this as proof of the condition stated.
2. If there are any problems with the device upon receipt, we will go through USPS INSURANCE to get your money back (as I will have proven that the device was working upon sending). Priority mail includes $50 of insurance.
3. I will use escrow, however: You must pay the (nonrefundable) shipping charges directly to me before I ship the device. This is usually around $5 to $6. In addition, you will have to agree to cover any currency fluctuation (so that when the escrow is released, I will have received the equivalent of $50).
Feel free to ask any questions in this thread, in PM, or on Freenode IRC (my nick is danieldaniel).
