There is a company in California, called Earthstone (they have a website), that makes wood-burning ovens. They are not cheap, and because they are so heavy, I know they must cost a fortune to ship, but they are a very realiable company. Check them out.

I have one of these in my backyard. (See attached photo.) Total cost from Earthstone back in '99 for the Model 90 was $2823.00. This included shipping, about $300, and the following accessories: Cooking video $25.00, Fire starters $48.00, Ash stick $10.00.
It took about another $8,000 to have a contractor build it.
Since I live in Seattle, the structure needed extra support for our earthquakes--included with the instructions. The 6.8 we had in February 2001 caused no damage whatsoever.
It comes with two videos, one for assembly, one for cooking.
I am totally satisified with their oven and their service during the sale.
I've used this to prepare pizza, bread, duck, chicken, steak, roasts, and this past thanksgiving's turkey (11 lbs cooked in just under 2 hours). At the end of a pizza party I'll throw all the leftover ingredients into a paella pan and make paella.
I have a pizza garden planted on each side. This includes: basil, rosemary, chervil, lavender, roma tomatoes, golden sage, French sorrel, French tarragon, thyme, parsley, French lavender, marjoram, sage, oregano, Greek oregano, cilantro, chives, and dill.
I'm glad I didn't get one for inside the house as occaisionally, the smoke comes out the front rather than the chimney. Guess I should have been a boy scout. :)
