Might I add, get a crockpot from Goodwill.
The thing gets hot, cooks food slowly, very simple principle. No need to buy a brand new one.
(same thing for a clothes iron - wow, look at this piece of metal get hot and take the wrinkles out! nowadays I use an iron about 3 x's a year, but even when I used one almost every day, I couldn't see spending more than a couple of dollars on one)
