I just bought some slab wood from a pallet manufacturer for $95 a cord, and I have to admit, it has me scratching my head a little over all the work I put into rollin' my own. This is all hardwood, and the vast majority are of a size that I can simply toss in the Tarm. It's quite green now, but it still burns when I mix it with the last of my dry wood. It does seem like a really good fuel for the price for a gasifier.
