Smoke, I've seen that concern for Blaz'n before. They've been making pellet grills since 2011 and are attached to a metal fabrication and powder coating company doing business since the 1970's. It's family run, with multiple generations working there.
Since they do the majority of the fabrication, all the assembly, and powdercoating/painting in-house, the only bits brought in are the controller and WiFi kit. They're about as solid as can be in my book ... they're not using as fancy a marketing platform as Mak or Yoder, and they don't relentlessly self-promote like some others mentioned in this thread (cough * RecTec * cough), but workmanship and a willingness to stand behind their product is what really matters at the end of the day.
I doubt anyone would cast doubt over the fitness of a Mak (if I ever hit the "redneck retirement plan" Powerball, I'd but a 3-Star General and use it as a built-in for an outdoor kitchen); that being said, the Blaz'n has exceeded my every expectation and I've gotten nothing but positive experiences with their customer service. I did my homework on them, everything from BBB data to even tracking down reviews of their metal fab company; I even ran their company in D&B and Hoover's just to gather a bit more data. I was satisfied with everything I found.
