And, assuming we are supposed to be posting in this thread at all. This is the most efficient cooking apparatus I've ever owned:
It costs about $100 on Amazon.com. I paid more years ago. It will pressure cook, brown, and simmer. Other stuff too, but that's all I use it for. I use these three features. The damn thing will (on the browning setting) fry potatoes quicker and easier than a frying pan. I cook the potatoes, remove them, and drop in a couple of eggs. Breakfast. It will also fry bacon.
As I type this, I'm simmering a beef soup. On simmer, it is similar to a slow cooker, but takes about two hours, rather than eight.
It also cooks rice, but that's not its best use. Buy a cheap rice cooker and you've got just about everything.

Late edit: The alternative is to just do the traditional stuff. Get a cast iron fry pan and a couple of cheap stainless steel pots.
The option I posted about though is walk away and let the food cook while I do something else. That's what I'm looking for.
