I recently got my hands on a Smokey Joe Platinum and found it makes a great Mini Smokey Mountain. The guy I bought the Smokey Joe from had done some nice mods (temp gauge and two additional smokey mountain vents on the bottom for better air flow).
I bought a WSM Pro-Q stacker off e-Bay and turned it upside down. Fits like it was made for it. I also added a second grate, a heat defuser (16" pizza pan with holes drilled in it) and a water pan. This thing is awesome! Keeps really steady between 225 and 275. Very controllable with the mods I've got.
Here are some pics.
By the way, my local ACE told me these were coming back.
