I looked at the Brickwood Ovens form along with a whole bunch of other options. The biggest problem I had with them was the height of the cieling inside the oven seemed way to high for pizza. Also, they had zero customer reviews. I liked the overall look, but I also noticed it had to reduced opening to hold heat in )although you could do a custom job and add that).
I decided on the Roudboy oven for the same reason you cited. Not a fortune, moveable, makes great pizza. I bought mine and love it, my next phse is to cover it in stone veneer to go with my new BBQ island.
Roundboy has GREAT customer service and were very helpful and responsive. Anytime I needed something I just called one of the owners on thier cell phones as listed on the site.
