any one have success with small format piza ovens? this one is $180 but i guess you might as well just get a piza stone and use the oven. 

We bought one of these during its Kickstarter campaign. Not exactly what you are asking but maybe interesting nonetheless. Tons of delays though and we haven't received it yet (although earlier people have so its not a total scam.)

If you do click through note the 500 degrees they tout is in C, so 930 Fahrenheit.
