On a side note I use a Thermos Nissan Cook N' Carry:
You just pre-cook you beans/meat in the inner pot, take off the heat and place in the outer pot. Its main advantage is that it saves on butane or fuel.
I cooked a pot pinto beans last week. After the usual pre-soak for 8 hours I boiled them for 15 minutes and then added them to the outerpot for about 3 hours - cooked to perfection, without any risk of burning them! I would have used 2 hours of gas otherwise.
Its not cheap but it well worth it. Here's the amazon link
