Check out the Ainol Novos 7 Fire. About $175, benchmark is very near the Nexus 7, comes with 16gb internal, hdmi out, sd slot, and 2mp front camera 5mp back camera.
Comparison video. I'm buying the Fire, the little bit more processing power from the Nexus 7 isn't worth giving up expandable memory, better cameras, back facing camera, and hdmi out...plus it's cheaper. And btw the video is a little old, there is an official firmware update for the fire 7 bringing it to android 4.1.
Do not buy! I bought two Ainol products and had to send the Fire back to China due to poor QC. I bought a Crystal which advertises an MVA panel and shipped with a TN. Go to Slatedroid to see how many Crystal and Fire bricked tablets out there. Ainol is nowhere near a reputable company. I now own a Nextway F9X, however one needs some technical expertise to bring out the best features of this and any China tablet. Stick to the major brands if you do not want to open the back cover or install custom roms.
