I am new to smoking. I am stuck between the 2 and 3. I think I am leaning towards the 3 though. My question really is, what additions besides the unit should I get? I am an avid hunter and fisherman. I enjoy jerky and snack sticks. I plan on doing a lot of deer and goose jerky/snack sticks and possibly summer sausage with the unit. I have also read many different suggestions to either get a conversion to use dust chunks or chips, is it better to use a certain one? What books do you suggest to get me started also. Any help is greatly appreciated. Thank you
