Interesting thoughts on whether these saws can be used for logging. If I was falling and bucking for helicopter logging, long ways from the truck I would want new name brand OEM or even working under a tower. But so many jobs these days are small jobs clearing land for home owners and such, skidder and cat logging, I'd be happy to take big blue to any of these type jobs.
Big blue would make a good landing saw, bucking and bumping knots.
I went to our local saw shop a couple weeks back, there was a 661 for sale, the tag said $1,600+, I just rounded down. So the full price plus sales tax would put it to $1.700 and then some! Not sure how much the 661 is without the extra charges for being in Alaska.
These days all I do is firewood and a few cedar shake blocks, the G660's look like good value for my dollar.
