I use a conventional counter-top rotisserie made by Sunbeam, model 4785. I've read reviews of it that knock it badly, but frankly, they must be from cooks who have no business being in a kitchen.
It works perfectly for me and produces birds that are perfectly cooked and falling off the bone tender.
It's a snap to clean and cooks FAST! When I'm in the mood for Cornish hens, it also cooks them perfectly. Serious Yum!
The complaints I read about it say:
1. It's hard to clean. (Not true. Takes me 5 minutes after soaking the parts that get meat cooked to them...just like a pan.)
2. Too small (For what? An ostrich?)
3. Heat all goes out the vents (Well, it's supposed to grill the food, not bake it. The heat is designed to go out the top and let the element cook the food with radiant heat)
4. The food basket cooks unevenly. (Ok, you're supposed to either put the food in the center OR the outside, depending on if you want it to cook quickly or longer. Not both at once.)
Here's the beast:
