I have that same coal, but I picked it up directly from Robb while I was up in his neck of the woods. I don't have a lot of coal experience but its real good IMO. I priced it through HH and its way too much for me to pay. I want to find a bulk supplier, I'd consider switching from propane.
That is another option, I built my own propane forge and love it! Just light it and go, no fuel to add, no fire to tend. Just a thought.
