I am another in the "love it" camp. I do a lot of large group lunchs (mtb Trail maintenance days) which the slow cooker comes in handy for, so much I've had to recruit friends slow cookers for even larger events!
Our house favorite is Butter Chicken in the slow cooker. Befor I had a slow cooker I hated using chicken thighs for butter chicken as I found the rubber-y tendons unappetizing, however in the slow cooker these parts of the meat are melted away leaving very flavourful and tender meat in my butter chicken sauce. The big win is the $$ saved by not having to buy expensive chicken breast meat.
I do meatless stuffing in my slow cooker which is always a big hit too.
