I'm sure I'm in the minority here, but there are a couple things that bother me too much about the Bell Fab's that stopped me from considering them when I was in the market. I ultimately settled on a Blue Smoke Smoker from Big Phil's which is another high quality 3/8" pit at a great price.
First and most importantly Craig is a die hard "bottom up" guy, as in his pits are designed for the heat and smoke to flow from the bottom of the cook chamber up. A Youtuber named Smoke Master D bought one of his pits and Craig mentioned to him that he strongly believes that is the best design and is how all of his pits are built. As such, since the heat source is coming up from the bottom, it is recommended that meats be placed fat cap down. I don't like that, I wanted a true Texas style "open pit" with no baffle, designed for the heat and smoke to flow over the top of the food, which means you cook fat cap up (like all the Texas top 50 places.... Franklin, Goldee's etc.)
Second, I don't know, there is something about the aesthetics of the Bell Fab's that bugs me. I just don't like the way they look compared to other traditional flow offsets like Big Phil's (Both his regular line and his Blue Smoke line), the Work Horse Pits, the Mill Scale, the Franklin and several others.
I'm sure the quality on the Bell Fab's is outstanding, and I see most owners are very happy which is all that matters, but I'm just giving an opinion from the other side of the coin.
