As another POSK owner (my K7 was one of the first batch made in Indonesia, so it didn't suck as bad as the later ones), you will not regret upgrading to whatever size KK works for you. I learned a lot about ceramic smoking and grilling on the POSK, and back then, their Forum was almost as awesome as this one (til RJ started "banning" people left and right). You know in your heart what the right thing to do is, just follow your conscience!
