Hi all, I just bought an MES 30 Digital today and have been looking at the amazenproducts.com website to buy one of their products. I get that the AMNS uses sawdust and that the AMNPS can smoke pellets or sawdust. I mostly, if not entirely, want to use this for cold smoking. Not sure yet if I'll want to use it for hot smoking, but it makes sense to me to buy the AMNPS just in case, however I'm wondering if there's a downside to this one while cold smoking sawdust. Not sure what the point would be to get the AMNS otherwise. I'm also wondering how people use these other than cold smoking and why. Do people use them instead of their smoker's wood trays or in addition to for extra smoke. Just trying to figure it all out! Thanks
