Ribs are easy.  3-2-1 method.  Smoke for 3 hours, wrap in foil for 2, then remove from foil for 1, or you can through them on the grill to blacken them, and firm them up a little,  instead of the last hour without foil in the smoker.  If it's baby backs, you can go 2-2-1.   I've had my Masterbuilt for about 1 1/2 years, and still use it all of the time.  Electric is so easy.
