I love Sweet Baby Rays with the honey in it.
Kroger's Sweet and Tangy!
My own made from scratch, otherwise Sweet Baby Rays, honey, with a touch of my hot sauce in it (and I mean one drop per 16 ounce bottle)
My favorite is KC Masterpiece
Catleman's best sauce I've ever used!
I like good old KRAFTS!
Everett and Jones BBQ sauce. Made in the SF Bay Area so I don't know how widely it is distributed. Apparently you can order it at super-que.com and have it delivered right to your door. I would have never thought of ordering BBQ sauce over the internet. Just too old, I guess.
