I purchased a Window (YuanDao) N70 Dual Core Tablet PC RK3066 IPS Screen 7 Inch Android 4.0 16GB 1G RAM. The price I paid delivered was $153. Which is good for a 1024x600 display. It took two weeks to arrive.
The down side is that you are dealing with a real Chinese company. Do not contact unless you write mandarin. Also in my case some of the defaults applications were designed for a Chinese audience, which is what you would expect. Do not expect support: sales, or technical. (at least in English).
If you do order I would recommend using the Shanghai post option.
