I think I only have one grocery store chain in my area, Albertson's, that stocks the right one. It is Kraft Carb Well Original and has the South Beach phase 1, 2, 3 label on it.
It has 2grams of sugar in 2 TBSP although 3 grams of carbs per serving. It might be the same product in a different label. It as 15 calories, 0 from fat, 390 sodium.
Sucralose (Splenda) is listed in the ingredients but so sugar and molasses. I can use this one just fine. You can also make your own barbecue sauce but I found this to be easier. I just buy several bottles at a time since it isn't my regular store and it tends to last me a year since I don't use BBQ sauce a lot.
