well i got one of todds' new tube pellet smoke generators and i must say it is well built and just as easy to use as all of it's predecessors. as for time of burn i filled up the AMNTS and got 4 hrs of voluminous smoke. when i use the AMNPS i get a longer smoke but i have to light both ends (and get about the same burn time) to get the amount of smoke that the AMNTS put out for me. i was excited to try the AMNTS since i have had trouble keeping the AMNPS lit in my upright gasser when using the flame but the only smoking i needed to get done on my day off was some BBB and i cold smoke that but i plan on trying the AMNTS on a bird next week. as a cold smoking unit the AMNTS worked great and put out lots of smoke and actually cut my smoke time from 10-12 down to 8-9 hrs due to the amount of smoke generated. if for some reason you have not gotten yer grimey lil' hands on ANY of todd's smoke generators you are truely missing out. i have been lucky enough to have worked with the AMNS, AMNPS and now the AMNTS and i can say that they have made me a cold smoking pro. i get predictable, consistent and flavorful results with no bitterness whether i am doing bacon, chiptotles, sausages or whatever i choose to cold smoke. from what i hear the AMNTS could be the answer to the propane smokers issues and from what i've seen so far, i have high hopes.
