I just picked up my first tablet a little over a month ago to take to the hospital when my wife went into labor instead of dragging the laptop. Picked up the Hisense Sero 7 Pro from Walmart for $129. It's VERY comparable to the Nexus 7 with the addition of the dual cameras, microsd slot, and cheaper. No problems so far.
1.3GHz NVIDIA Tegra 3 quad core
1GB DDR2 & 8GB on board memory.
1280x800 resolution
NFC, Bluetooth, mini HDMI, USB OTG
and a fairly long lasting battery.
Looks like the price went up, but I'd check in store. My local store still has a bunch at $129.

I'd definitely recommend it for the price.
