Sounds like a saw for manly men.
I was wondering about the 090 because I saw a video of a guy cutting off a rootball on a felled tree that was so big it took a couple of minutes to walk around to the other side of it.
I'm curious why $100-150 was considered only a pretty good price to buy this saw, when there is currently one being auctioned on eBay with the bidding already over $400. Shipping is $38 and it comes with a new extra bar.
