I have the 732, did not need the bells and whistles of the other models. It seems to be working fine check the reviews on Amazon, seems like I seen a lot of negative reviews on the newer models. Also when I took the pork butt out of the fridge it said IT was 40 degrees. So I think it is ok, I still use a thermoWorks RT301WA-N to check the meat b/4 pulling off the smoker, that was recommended by super Dave.
