I was on the same page till I got one. I found out I was wrong. Plenty of space to cook/smoke 17lb (cleaned) brisket in the LX size and if Green Egg seems expensive, there are few other alternatives that are the same type of Kamado grills and they are in the $600 price range for 18"-24" sizes in Home Depot or Lowe's... Nothing can cook steak as this thing, I absolutely guarantee you. I never use pellets, real wood is much cheaper and produces better smoke IMO but just as you said - different strokes for different folks...
I've heard good things about the Green Egg. I don't have any personal experience using one but you obviously like yours and that's all that matters.
FWIW, I didn't pay more than $600 (combined) for my 22" Weber Kettle Grill, Weber Spirit 3 Propane Grill and Pit Boss 5 Veritcal Smoker, which retail for around $1.5k (combined).
Never made sense to pay "retail" for any of these things because people are always selling them at huge discounts on CL.
I actually never use the kettle or propane grills to "grill" anything. Too messy to clean up and unnecessary IMO. I get the best results grilling my steaks in a cast iron grill pan on my stovetop.
I just use the "grills" to roast/smoke things that I can't/don't want to cook in my kitchen oven.
I've used both wood chips/chunks and pellets to good effect in both types of grills w/turkeys, chickens, pork shoulders, pork belly and both pork & beef ribs.
Looking forward to seeing how the vertical pellet smoker performs cooking some of these things in greater volume in the future.
There are, of course, offset wood/charcoal vertical smokers but they require a lot more attention and take up a lot more room than the vertical pellet smoker that I just bought, which I why I have never purchased one of those.
As long as it's filled and running "right," the vertical smoker (w/a 55# pellet capacity) could easily low smoke four 15# pork shoulders (and maybe even more than that) w/o the need to even look at it for up to 12 hrs (not that it would take that long) but, given the cost of that meat and my A/C nature, I'm sure I'd check on it every couple of hours anyway.
LOL!
Happy grilling/smoking and BOURBON drinking, regardless of how you choose to do it!
