Slow Cooker Barbecue ribs

I just tried this recipe today and this has to be the best way to cook pork ribs:

Ingredients:
Pork ribs
1 onion
1/2 cup brown sugar
1/4 cup vinegar
1 Tbs honey
and 1/2 to 1 bottle of bbq sauce.

Cut the onion into big chunks, mix the rest of the ingredients and pour over the ribs in a crock pot. Cook on low for 4 to 6 hours.
