I have been going back and forth on a couple of smokers to get. And thank you all that gave me feed back and helpfull info. This site is the best for help. So am going to ask for some more help and then it will be a done deal. I am going to buy a Bradly digital smoker. Other than the ovise how much difference is there between the four and six rack smoker? would it be worth 100 more bucks for the 6 rack one? Thanks for taking you time in reading this and giving me your info.
