I decided I would like a tablet, mainly for watching shows and videos on, and surfing the web. So I want one that is 10 inches and has expandable memory or a lot of memory to begin with, or both . Now most 10 inch tablets here are a lot of money, and my limit is around $200. So I found 2 tablets I like: the Ainol Novo 10 Hero, and the Zenithink C93. Where is a reliable place to buy chinese tablets from, and are those two I mentioned good tablets to get?
