I know I'm preaching to the converted here, but:
1. For the time and labor, cutting wood is a hobby for me and one of the main forms of exercise I get. I think I would probably cut wood even if I didn't burn it.
2. The savings for me is probably more significant than others. I have a 2400 square foot home with a 1500 square foot basement. The propane furnace needs to be on almost all the time if it's cold to keep up. Last year, we burned 7 cords of wood in a pre-fab fireplace, spent $800 on propane and about $900 on electric heat. The house was normally 63 degrees.
3. My Timberwolf was $4060 plus tax. Lines, sidearm and fittings brought that total with tax to $5300.
4. All my wood is free from farmers or neighbors. Most recently, I got about 5 cords of popple that was already cut to 8 foot lengths that I had to pick up about half a mile from my house.
