Interesting thread ... only read thru some of the many posts.
My take?
I got a Lexington 400 (from Walmart). I kind of like it, but there's been issues. First I had to have a new controller from day one ... ok, that happens. Customer service agreed and sent one out promising ~2 weeks for delivery. It came MUCH faster. Very good!
But, next it seems, I need a new temp probe, since the controller thinks the interior temp is at least 50F+ BELOW from what it actually is (I've confirmed this with multiple probes / thermometers / etc, incl the probe that comes with the unit.) I'm still waiting for the replacement probe, which should have come by now (the replacement controller came much quicker.)
But, OK, so sometimes you get a lemon. Customer service seems very good for this company.
BUT.... Overall? This thing is kind of a pain in the butt. Requires plug-in to electric, takes a while to churn the pellets into the hopper, on shut-down takes a long time to actually power-down, cleaning is a bit of an annoyance ... most video's talk about using a Shop Vac to clean it out (fortunately, I happen to have a vac with a hose I can use for that .. whew! .. I had no plans to buy one!)
I've yet to really see how it is significantly better than, say, a good charcoal smoker/bbq combo.
My last bbq was a cheap charcoal grill. I managed to do a decent job of smoking on it. It was, well ... eeeh. But, yet, I did reasonably well.
I have yet to try smoking on this one (waiting for the above) ... but worse, from what I've tried: the opening for flame-broiling is REALLY small. I LOVE flame-broiling steaks!!! But I can only do one at a time because this opening is so small. My crappy cheap charcoal grill was NO PROBLEM!
I'm probably going to get another crappy cheap charcoal grill to supplement this. I expect I'll continue to use my Lexington for smoking, Rotisserie Chicken (I read it is very good for this?) and maybe some other similar things.
But for Charbroiled Steaks, Hamburgers and the like ... no, I don't have high hopes for the Pit Boss. It just doesn't seem to do this stuff well.
