You can't really count your hours as value unless you're actually handling wood instead of working for money. For me, I'm handling wood instead of posting here or watching TV.

Anymore, time doing nothing is priceless. My downtime is certainly worth $10 an hour.
I didn't even add some of the other costs of burning wood. My wife would #### a brick if she knew what I spent on chainsaws last year, although I am getting ahead of the curve on that one. I am a little more selective about what I buy now. I am pretty well stocked on consumables. I guess any one of the several saws I bought last year probably would've done all my firewood cutting.
How many of us maintain a vehicle primarily for firewood? I do. Trailer? check. Splitter, tractor, bobcat, etc? Eventually. High end, ultra efficient stove? I may eventually get tired of feeding the dragon. Granted lots of those things have other uses, but the costs add up.
For me, the rewards of burning wood are best enjoyed when the wood came in by my labor alone. I would rather spend the money on "tools" than energy. Every dollar you save burning "free wood" is really more like $1.25 because the money you spend on fuel comes after taxes.
Again, If I had to pay for wood, I think I would just sit back and pay "the man" as I suspect there really is no gain in paying for wood vs any other fuel.
