First, let me say that I have not purchased his rub/sauce recipe. There are sooooooo many great free ones out there that I just do not see the value in it for me.
That being said, when you buy his recipe you have to look at it as a donation to keep his site up and running. He has a really good site and forum that is very valuable and has helped a lot of new smokers. So, I would encourage anyone who has purchased the recipe to refrain from giving it away or selling it for a discounted price. Instead provide your review/opinion of the recipe and whether you thought it was worth it or not.
I frequent his site once and a while, but not really that much as I spend most of my time on this site that is tailored to my smoker. Now, if Steve came out with a Cookbook or something similar to used to fund this site, I would probably spring for it knowing how valuable this site is to me.
I have a ton of rub recipes that I have purchased and really enjoy. So, I haven't really made any of my own yet. I have my favorite recipe that I order by the five pound bag:

As far as sauces, I really like the Sweet Baby Rays Original. I have tried his other ones and didn't like them as well. I have also tried Famous Dave's and Hunts/Kraft versions and for me and my family we like the SBR's Original.
This is my 2 cents anyhow.
