Tablet comparison prices on amazon?

Okay, so heres the thing. This is the type of tablet that I want to get: http://www.amazon.com/...002OOWC4C/ The cheepest one is 45.00, but I think that that's a bit too cheep. Plus, he once sold a stolen iPhone. The next price is 50.00. I'm not too sure about that one because it 1) Has a scratch and 2) is a bit cheep. The next one is 102.00. It seems fairly reasonable but I only have about 80 saved up. Help please? Should I take my chances with the 45 or the 50, or save up more?

You get what you pay for.
