I got my little pizza oven on Kickstarter and was an early backer so it was even more steeply discounted
I've used it for much more than pizza, searing a sous vide steak, roasting veggies, I made a killer charred Tomatillo salsa a few weeks ago.
It get to full temp in around 10 minutes, and you can maintain various heat levels depending on how much and often you fill the hopper.

Apparently the model I have has been discontinued..
