I have three. Two of them are so old that I don't think you could buy them any more, but they're by West Bend, and have a burner that the metal pot sits on. The nice thing about that is that you can brown the meat (or whatever) right in the pot rather than dirtying something else. They're oblong shaped, and even somewhat decorative (if you still like avacado green and harvest gold <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />. They are very basic. The one I use most is the Crock Pot brand, and has a removeable stoneware crock. It's also oblong shaped (which really works best for large hunks of meat. This one is programmable and switches to "warm" after the cooking is done. I used it most when I was working so the food wouldn't overcook before I got home.

As far as only cooking for two, I'd still use a larger one because the leftovers are easily frozen, which is what I do now that we're empty nesters.

I'd suggest you go to Amazon.com and do a search. They have everything, and each item has tons of reviews by real consumers. That will help you to decide which is right for you.

Good luck!
