Help !! Buying an android tablet !!

I will purchase a tablet because I want to use it for reading E-book.
Requirement: screen, 7 inch is enough for reading book. OS at least android 4.0. About other performance parameter, I have not much request.
I checked out and find this tablet http://www.tinydeal.com/ainol-novo7-pxzu25-p-65555.html, fits my requirement, seems sending a TP-link router with this product. Does this tablet from China work in good quality? I need some information from you.

Ahh..could you take a look for 10.1" one, it may make you read easier
Take a look Lenovo IdeaPad K1
price 215$ - 470$
