I see those performers on sale right now at best buy too.
I loved my gasser. Get off work and fire it up with the press of a button, in less than 10 minutes it is ready to sear. Of course, I've never used a quality charcoal either.
I have both a propane and coal vertical smoker, the propane smoker never gets used.
The closest thing I ever had to a kamado was when I first started smoking I built one out of a terra cotta pot. I saw the design on good eats. I made mine a little better.
That thing held heat and cooked so well, I've been looking for that experience ever since. I cracked during a move otherwise it would still be burning.
