Baking in alternative appliances

The circulars are carrying ads for roasters, probably because you might want to use one for your Thanksgiving turkey.  The ad I'm looking at has an eighteen-quart Aroma roaster oven.  I can't see clearly, but it looks like temperature settings go up to 450F.  (The price is $39.99, "Orig. 89.99. Plus bonus electric gravy boat.")  I got to wondering how it would do for baking bread.  Has anyone tried one?

I do have a couple of crock pots.   Any possibility one of these would prove useful?

Just wondering....     Rosalie
