Pizza Oven build

[Robbo81]

Hi All,

I am looking to build a pizza oven that could accommodate 2 - 3 pizzas 12cm dia
something like this.
Perfect pizza oven on Yahoo!7 Video (http://au.video.yahoo.com/watch/2972929/8334268)

its the better homes and gardens one.

can some one give me a indication on how much would this weigh and cost?
I know its a how long is a piece of string question, but if you can give me some ideas it would help.

Thanks
