Being an old smoker, and never used a pellet before, I too had my doubts. I assumed that pellets were like PVC, just a bit of wood and than added filler. I assumed there would be no controls as to what I got so I should look for those people here and learn who had the best.
Well If you have not already guessed there is a load of folks here doing the Amazin smoker and pellets.
Todd of Amazin Products does extremely well at maintaining a very quality product. You will have troubles with some pellets, some say because og the woods density. But that are more the exception to the rule than the norm.
I bought a tray and some pellets from Todd. I use it as I do a cold smoker or really more like an auxillary smoker. Sometimes its frustrating as all get out, but most days its chugs along like a champ. It does require a good ventilation here on my MES30 and MES40. I have not seen a need to use it on a larger pit yet.
The biggest thing you need to realize about the pellet tray, much as with the entire smoking opperation. If you need to spend 10 mins or 30 mins to get it ssmoking correctly, its a small amount of time to ensure a good 6 to 24 hour smoke. Why would you need immediate gratification in smoking? It goes against the very grain of what you are doing. Low & Slow.
Once you acclimate to the pellet tray, you'll wonder why you didn't make it yourself long ago. Its well worth the money.
BTW if you plan to cold smoke, get a dust tube instead of a pellet tray.
Bon Chance, I hope you enjoy the realm you are about to enter. Its really a load of fun.
