I just received a custom offset from Pits By JJ. It is extremely well built and cooks great. I have never seen a Gator Pit in person but they were one of the pits I researched before buying. Gator Pits have a great reputation so I have no doubt that they are worth the wait.
However, I can tell you that Pits By JJ built a fantastic offset that I will be able to pass down to my children's children and they answered all my phone calls and answered my emails within one day. The Build quality far surpassed my expectations and they are a bit less expensive than the bigger names out there like Gator Pits and Klose.
