Bread-Bakers v097.n044.13

Does anyone have experience with wood fired ovens at home? I've been
considering having a small one built say, a 10"x16" baking surface for my
back yard. I'd be interested in approximately how much it would cost to
build, if kits are available, how you control the heat and how far in
advance you need to build the fire to start baking. 

If you know of a book that describes wood ovens, please let me know.

Thanks,
