Bread-Bakers v105.n016.13

I'd like to ask Dave Barrett to give us an evaluation of his gas convection 
oven, including the make and model, not only for bread baking but other 
cooking as well.  Ten years ago I was interested in getting one, but could 
only find one that had to be vented to the outside.  Is this true of your 
model, Dave?  Does it use natural gas or propane?  Thanks for the info.
