I know this is digging up an old thread, but I feel it is important to let people know that HBT is a reputable company. Their business has grown exponentially over the last 2 years. I don't own an HBT, but I know several people who do. They are all satisfied with the product. I am saving up to purchase one of their Gameday models next spring.
The guy who started HBT supposedly worked for one of the "other" mentioned companies, and didn't like how the smokers were being designed nor how the company was being operated. He has solid backing by another business man, so like I said, reputable.
They currently have a large backlog, so if interested you might want to call to see how long to get one. The owner will talk to you and go over all of the design with you. They can do any custom work required also.
You can research them on YouTube, Facebook, and Twitter. Very good quality for the price.
I have my eyes on the Ultimate GameDay.
Anyway, hope this helps?
