Lumberjack has a great reputation for pellets as they are 100% of the wood they say they are, no oak fillers, they are also available in several retail outlets. I also now see Kingsford advertising 100%, no filler pellets but have not seen them yet. The pellet smoker revolution is in full swing so I would think the availability of great pellets is not far off. You really want the pellets to be 100% of the wood advertised, you really have to look at the fine print. If they say 100% hardwood it is a mix of oak filler along with the cherry, apple, maple etc.
