I took one look at the guy's e-bay photo, and saw a pit-bull on a chain. That pretty much says it all. I love dogs the way some of you guys love your saws. Never put a dog on a chain, 'specially a pit-bull. I've owned dogs all my life, hunted, bred and trained them. Put a dog on a chain and he's frustrated and only half the dog he could be, guarranteed. As far as chainsaws go, you sold it too cheap, to a dumbass. Better luck next time,,, and I'd check the guys' picture first. If he's dumb enough to put a picture of a dog on a chain for his ID, he's not smart enough to do business with!! Good luck, and that's one heck of bummer. Ask e-bay and I think they will remove it for you.
