If you have the funds, one of the best is the All American 921 21-Quart Pressure Cooker/Canner @ $290.00. It's a deluxe model that is SUPER safe.

I own the Presto 01781 23-Quart Pressure Canner and Cooker @ $90 bucks.
Its a good performing entry level cooker. It doesn't have all of the safety bells and whistles that the American has, but it works well if you stay on top of it.

Again and I CANNOT stress this enough. Can OUTSIDE!!!!!!

I can post a picture of what happens when a cooker explodes on the stove. Its not pretty.
