We were actually quite surprised with our success.  We tried the recipe a second time and placed the sauce in the smoker while the ribs were finishing up and THAT was a great idea.  The trick for us was using ketchup without high fructose corn syrup.  A little more expensive, but well worth the taste.  

1-1/2 cups brown sugar

1-1/2 cup ketchup (we use organic)

1/2 cup red wine vinegar

1/2 cup water

1 tablespoon Worcestershire sauce

2-1/2 tablespoons dry mustard

2 teaspoons paprika

1-1/2 teaspoons black pepper (freshly ground)

2 dashes hot pepper sauce (I add the two dashes...Dave usually adds more hot sauce to his ribs)

Load the blender with the ingredients and blend away.  We then cook it on the stove over a low heat, don't scorch the sugar.  Add them to your meat and grill or smoke until done!
