Don't get me wrong, guys. I understand that sometimes the easiest path is to not reinvent the wheel, especially if you can get your hands on some pretty good wheels. I also know that putting good rubs and sauces up for sale is a great way for teams to help pay the expenses associated with competing and I admire those who have decided to put their proven products on the market.
The down side is that there are many products out there that have no proven track record of success but are heavily marketed to the barbeque community. Sure, every target market is going to have it's share of companies that are only trying to make a buck with little or no real working knowledge of that market and it is that type of business that I have no respect for.
Personally, I would never by a rub or a sauce from any source that wasn't actively cooking with their own product.
