I went with a Horizon as my first offset smoker. Before this I used a uds 100% of the time. Since the purchase of the Horizon the uds has set idle. I love the taste of the product on the Horizon using wood as a fuel.
They are very well made and hold heat extremely well. They are made of brand new 1/4" steel and are VERY HEAVY. My 20" RD special weighed in right about 475 lbs. I can certainly see this lasting my lifetime plus my kids. This thing is an heirloom piece I do believe.
The folks there are really awesome to work with. They are definitely a customer oriented company and will do all the can to please you.
The only thing that disappointed me was their therms. One thing was "made in China" I wasn't to pleased with that plus they were far from accurate. If I were to do it again I wouldn't order one with their therm. Instead buy a Tru-Tel and mount on the Horizon.
Here is mine.
