Some of the links on this forum allow SMF, at no cost to you, to earn a small commission when you click through and make a purchase. Let me know if you have any questions about this.
I have a Char-Griller Akorn that I've been quite happy with. Both names used to mean cheap fairly low quality products. Char-Griller seemed to have stepped up with their quality, at least with the Akorn. You won't find a better Kamado type smoker/ grill for the price.
Char Broil has some decent products, mostly their charcoal grills and smokers. Not great but functional and CHEAP. Their 20" WSM competitor is only about $200.
Char Griller is a step above, definitely more engineering goes into their products and making necessary design revisions based on customer feedback. They're a budget brand too but supposed still family owned out of Georgia.
