You're in the Dallas/Fort Worth area? You should definitely check out Big Phil's Smokers offshoot brand Blue Smoke Smokers. He's located in Caddo Mills Texas, which is right in your area.
His Blue Smoke Smoker brand offers what seems like the best bang for the buck for a back yard offset... it's a 24x48 cook chamber with a 24x24 round fire box. The Pipe used for both the cook chamber and the fire box are 3/8" thick steel, while the end caps, collector and stack are 1/4" steel. The base model includes a single grate, and single Tell True guage for $1,700.00, which is right in your budget. It has a huge 6" wide 42" long stack. He also offers all kinds of add on's at very reasonable prices. If nothing else I would HIGHLY recommend you get the stack damper added as that is not standard, but it's a $100 add on. That's all you need.
Bell Fab is nice too, but Big Phil's/Blue Smoke Smokers is much closer to you. Another thing to consider is how you like your heat and smoke to flow. Think about cooking a brisket or a pork butt... do you prefer fat cap up, or fat cap down? If you like fat cap up you want a traditional open pit design that cooks from the top down. If you like fat cap down you want a bottom up cooker. Big Phil's Blue Smoke Smoker is a traditional open pit design (meaning no baffle, no tuning plates) and is a top down cooker. I understand Bell Fab's are Bottom up cookers as that is Craig the owner's preference. Both are good, which is better is based on your own personal preference.
I'm firmly in the top down cooker camp, as I like to cook fat cap up. I have a Blue Smoke Smoker and couldn't be more happy with it. I'd buy it again in a heart beat. Mine was a lot more expensive, but that's because I added just about every possible option, but it was still only $2,600 even with all those options. The pit draws like a freight train, and keeping a screaming hot coal bed is super easy. I also love the way it renders fat... the huge stack causes a ton of airflow and convection which just renders fat in an incredible way, much different and much better than any other pit I own, including a reverse flow stick burner I have.
