Ahh, we think alike my friend. I am in the same boat.
I've had a few pellet grills. My most recent one was a Pitts and Spitts 1250. An absolutely beautiful smoker. 300 pounds of authentic Texas steel. But I didn't like the food that came off of it. For me, it got an 10 in build quality and a 5 in food quality. You could make good food with it, but you had to get creative and wrangle the flavor out of it.
From everything I've read, the two gravity feeds on the market right now are the exact opposite end of the spectrum: great food, poor build quality. I have looked at the Masterbuilt a few times, most recently with the upgrades, and they are indeed built like your typical traeger/Rectecq/pit boss/etc. Flimsy. If your dog jumped on it, it would probably dent the smoker. I'm currently drinking a Coca Cola that is made of a similar gauge metal as those smokers.
That being said, I'm still going to buy one because they are the only game in town right now. Even if they were the same price, the Chargriller seems better than the Masterbuilt in every way. Except looks. The Chargriller is fugly. But it seems better put together and it's cheaper, so they get my money.
Once Weber stops hitting the Smokefire pipe and brings out a gravity feed, it is on. I will buy one the second it's available. Gonna be epiiiiiiiiiiiiiiic.
