I got a Smokey Joe gold had it for like 8 years I think, never seen a green one, but ironically enough, I LOVE that little pit. It's big enough that you can go 2 zone for 2 fatties or a meatloaf but it's little so it's perfect to cook like say a pack of brats direct.. and since it's so small mound the coals WAY up to the grate and SLAM a steak or 2 at nutso temperatures for cheap. I'm looking forward to adding the Mini WSM mod to it. I don't know how big of a crowd you got to feed, but honestly this thing has turned out to be my most every night of the week pit, it's too economical man. But like I say, I don't get upset at my 18.5 Weber for being too small sometimes I wish I'da bought the 22.5 but I don't find myself needing it too often and if I do I can always fire up the Joe Next to my other little kettle.
Kick off the WSM for a fatty or 2, no way.... Either grill, no prob man.
