I have two kinds. One for cooking on a stove top or fire, and the other is my baby.

The Cuisinart Electric/digital Pressure Cooker.
LOOOOOOVE IT!
I am burning through my food storage, using it probably 4-5 times per week.
We have soup for snack after-school and it makes a champion lunch that is hot and ready when we walk in the door after church.
You can braise and saute in it as well.
Oh, and it keeps your food warm for 14 hours once the pressure releases.
Maybe this post should be on the "what I will miss at TEOTWAWKI."
