Kamados are good but they are definitely finicky to set up and temp control. You can overshoot the temp really easy and its hard to get it back down. I got one fo the standard home cheapo acorn kamado grills, It holds the heat well (Longest smoke was a 250F for 12+ hours), and definitely worth the price, but setup is definitely not as easy as a pellet grill or one of the more expensive ones. The cool thing is when you do learn it, you can use the thing for many things such as an "oven" in the summer (roasted a big beef roast at 350F for 3+ hours last year) pizza oven, great in summer, the round shape kind of acts like a brick oven. Good is a pizza stone, but better is a steel 1040 1/4 in plate cut about 2 inches smaller radius. I have done this several times last year and the stuff comes out like a brick oven pizza 600F+. You can also use it as a wok heat source with the top grill removed. Jut get the correct size wok pan, and you can have perfect stir fry at those high temperatures. ( I have never tried this yet but saw videos)
Oh and they do sell 3rd party upgrade kits for $100-200 that basically install a little computer fan to the baffle and connect to yoru wi-fi and computer or cell phone for complete automatic temp control, but I never bothered. 1/2 my fun in doing this shit is hanging out outside, with a beer in hand just fucking with it/watching it, taking dips in my pool in between.
