We love our slow cooker. My wife went and bought a fairly high tech one, that will turn off the cooking phase after the programmed time, and go to a "warm" setting. Just this week, she set down a pork shoulder for kaluha pig prior to bed, and it was perfectly done, ready to shred, for dinner the next day. The beauty of something like that is, there's plenty of left overs, and they freeze well in a vacuum sealed bag.
She's got great roasted chicken, beef stew, and several other recipes. Slow cookers get a bad name because working class house wives pop a protein with a can of Cream of <insert here> soup, and call it a meal.
