I bought this tablet a few months ago:
http://rcatablets.com/tablets/7-4gbI did pick it up at Wal-mart for $70USD... And I would say it is certainly worth that price. I do wish that they had the 8GB model at the stores I go to, as I could have used the extra memory. If anything that I have encountered, having to watch what is loaded into active memory hurts the most. 4GB is just barely enough for the device. Even with memory cards to store content.
As a cautionary word, I have not attempted to stream video/Netflix or anything, thought it is apparently capable. And I am not sure if you can hook up a keyboard to it. But it had Android 4.1 on it and a decent processor. For me it is mostly used for viewing books/pdfs on the go, the internet when I'm not at my computer or running apps/games off of Google Play. All of which it does worlds better than my old and more expensive Nook Color.
Would I have liked a bigger, better model? Yes. But especially for it's price I find it very good for what I wanted, and I'm quite happy with it. Just be sure to get the 8gb model....
