I have read numerous discussions about the AMNPS: pros and cons. I am very close to purchasing, but at the same time, I have been satisfied with my results using wood chips in the tube. I do get frustrated with having to add chips every 1 1/2 to 2 hours, which keeps me from putting the meat on and getting some sleep at night. But the overall flavor and results have been good. Would my purchase of an AMNPS be justified? same flavor? same results? is the sawdust as good as chips? Thanks for any advice.
