It's on it's second year and has been well worth the investment. The heavy gauge construction is exactly what I was looking for. Porcelain coated grills are also a nice touch.
It needed mods to make it really work. I put in woodstove gaskets on both box and grill doors, and used high temp firestop sealant on the joints. 
This SOB SMOKES! 16hr full brisket came out KILLER! As does any other smoke session.
One regret is that the grates are not adjustable, so when using as a grill, temp. adjustment is only with dampers and fuel supply... you have to be expert on open grill to make it work.
Other than that, I am pleased as punch. I do wish they would come up with a hanging tray for grilling, so the charcoal distance to the grill could be adjusted.
