I spent about $2000 to upgrade to the Fireview. I now burn less wood and propane, the house is more comfortable and I save at least $1000 per year. If I spent $700 to upgrade my saw I wouldn't use any less propane or wood, the house wouldn't be any more comfortable, and I wouldn't save any more money. I suppose I could take a couple seconds off of each saw cut that I make to process 4 or 5 cords per year, but, beyond that, I don't see how my "home owner" saw is holding me back any. I also haul my wood with a 41 year old truck. A brand new one might haul some more wood and do it a faster, but it would cost more to insure per year than I paid to buy the one I have and just how much time can I make up in a less than 5 mile trip? For me, the economics just aren't there for high end, new pro stuff. If I used these tools all day every day and my livelihood depended on them, I would have the newest, best and fastest, I could afford.
