You want a Weber Smokey Mountain. Either the 18" or the 22" depending on your budget. 18" is big enough most of the time, but the 22" can comfortably fit three racks of ribs per grate, two if they're untrimmed spares. Pretty fuel efficient versus an offset or pellet burner but makes way more smoke than a kamado. And it's a Weber product so it'll last damn near forever if you don't leave it sitting dirty out in the rain. The porcelain coating will outlast the grates. If you don't like it you can resell it at a decent price.
