Try THIS, very, very good. Just had it last night, awesome stuff. It's not hot, but it's good. Make sure to let it in the fridge for a day or two before you cook with it.
If your in the midwest head to Montgomery Inn in Cincinatti for the best BBQ!
I made some of this last night and stuck it in the fridge after I read this. Tasted some of it today and it might be the best bbq sauce I've ever had. Boston butt will be done smoking in about 5-6 hrs. It's going to be fucking awesome. Thanks for the link.
