Mine is very cheap, don't remember what brand. It's one of those most basic ones. I don't even remember when and how I got it.
I strongly recommend getting one that has a timer - you can set when it starts and finishes cooking. I work full time, and it's impossible to use it during the week since I'm out 10 hours a day. I only use the crock pot on weekends,
which defeats the purpose of having a crock pot.
