Let me start by saying I have seen pitboss smokers at trade shows but I have never used one. However, they are made by Dansons. Pitboss is their budge/china made line. They also make Louisiana smoker (a higher end line) and some others. We have used a lot of different models of those.
I also really like Danson's service/support. I was helping a guy with an issue once and when the first guy who answered the support line couldn't figure it out, he transferred me to the engineer who had actually designed the unit, who figured the problem out in about two minutes. Don't get to talk to designer engineers at very many companies...
So, I think it would probably be a good starting smoker - but hopefully someone who has more experience with pitboss will chime in.
Note that there a BUNCH of models of the pitboss 700 (D, S, FB, SC). I don't know the differences among them. I think pitboss smokers are all on analog controllers - so no digital readout. Not a huge issue - we used analog controls for years, you just have to learn where to set yours. I prefer digital, but that adds to the price. In either case, you will want to use a good digital thermometer. I really like the one from
Camp Chef (best probes around, IMHO), but maverick makes one that has two probes (one for the meat, one to measure grill temp - helpful if you have analog controls) but Maverick's probes are terrible (poor design, fail a LOT, but the company will usually replace them free/fairly cheap).
Danson uses a side burn design on their smokers (like on a Yoder). That means the pellet auger is only a couple of inches long and it drops pellets down into the burn pot. The side design also makes it really easy to use as a flame broiler (there is a plate that slides open to let you flame grill on the burn pot - not sure if it is standard or an option). I have heard criticisms of side burn design because the smoke/heat comes from one side and flows across the grill, but I have never had an issue with it. Pellet smokers use a fan to push air into the burn pot, so the heat/smoke are fan driven, kind of like a convection oven. We took some measurements on a bit danson (cs680) and when the temp was set to 200, the difference across the grates was about +-5 degrees. I think the difference might get bigger if you run really hot (450 degrees+) or open the flame broiler, but I personally don't do that (not a good use for a pellet smoker).
A lot of other companies (like Traeger) use a bottom burn design that puts the burn pot in the middle of the smoker. Some argue this gives better smoke/heat distribution (I have owned bottom burn smokers and that is not my experience, but opinions vary), I personally don't like those designs because requires a very long auger to push pellets into the burn pot. More finicky, especially to shut down at the end of a smoke, and much easier to have an auger fire.
Camp chef also uses a bottom burn design and they recently added a feature to allow you to dump the burn pot without disassembling the unit, which can help address some of the shut down issues.
So, good luck with pellet smoking.
