I recently purchased an 8" tablet with Android 2.2. My main reason for getting it was for an e book reader and as a web designer to test my web sites on a mobile device. I also wanted to become more familiar with Android.
I purchased it from Yuqi Electronics which I found on Alibaba, they offer a 1 year warranty if they tablet should stop working. I paid $213 which included UPS shipping and paypal fees. It's a nice little tablet my only issue is it does not have Google Market on it and I'm having a hard time getting some apps to work.
