I currently have:
1) an Oklahoma Joe offset smoker, charcoal grill, gas grill and gas burner combo
2) a Pit Boss Vertical Pellet Smoker
3) a Japanese binchotan grill for yakitori and other ultra hot preps, this one is great and I got it from Amazon (note no American metal grill can withstand the heat of real binchotan coals and this is a good cheap substitute to more expensive earthenware grills)
4) a really nice, lightweight three burner gas grill for traveling/picnicking. I can’t seem to find the exact model but I picked it up at Costco in store for next to nothing, under a hundo, and it’s almost as nice as your Average non portable gas grill.
I‘m completely, 100% happy with my current setup. It’s very flexible and I haven't spent a lot, probably about the same or even a little less than just one of those overpriced Big Green Egg setups.
The two options I use the most are the gas grill and side gas burner components of the Oklahoma Joe and the standalone pellet vertical smoker. The two options I use the least are the standard American charcoal grill and the side stick smoker box on the Oklahoma Joe. If I were to completely redo my setup, I would DEFINITELY keep the vertical pellet smoker, Japanese binchotan grill and small portable gas grill but I‘d probably swap out the 4 in 1 for just a smaller gas grill plus side burner and a separate pizza oven.
