Best Cheap Android Tablet

Folks.... I am determined to enter into the Android Army. Previously an IOS user, I am very happy to carry a device with me that I know will be able to receive calls and texts without having to worry.

I am a modder at heart, however and would like a device I can play around with and do some e-reading. I've been thinking about the Nook Tablet as it's cheap and appears highly mod-able. I'm looking to spend around $200. I need suggestions from the army.........
