Where can I get a cheap tablet?

You generally just have to look around for deals. You can buy them from almost any PC Store. It depends on what you want as to how much it will cost. If you just want it for internet brousing and light use, get something like an Archos internet tablet. they usually cost about £200. But if you want one for heavy use, get an ipad or a Samsung galaxy Tab. These sorts of tablets cost around £400.
