Portable Charcoal-fed Firebrick Oven
Here in the Philippines, there is a company known for manufacturing firebricks and firebrick ovens as well. The inventor made it as a solution for the high cost of LPG-run stoves and gas ovens. They can also be used for smoking meat, one just has to cut the wood to fit in the pull-out charcoal box.
I am planning to get one as my very first oven, the standard for home bakers (the one in the image immediately below) which measures 15x15x14in on the exterior, 12x12x10in interior. It costs less than $400 (converted from our currency), almost the same as getting a La Germania or Elba LPG-fed oven. This company supplies and customizes for almost all of the restaurants of famous chefs here in our country. I can't wait till my order arrives. :)
They can ship to provinces far from the country's capital, so I guess they can ship abroad too, if anyone of you would be interested. Here's their facebook page: https://www.facebook.com/JyFirebricks. I am not in any way related to them, just a fan of their firebrick ovens. :)
