I just bought a stump grinder and need to buy a chain saw for those high stumps. I stopped by a Stihl dealer and they recommend nothing less than the new 650. Friend of mine drops trees and lives by the Husqvarna 385 and says I don't need anything more than that and probably could get away with a Stihl 440. He's heard bad things about the 460, which he says is comparable to his 385. Looking at some specs, it looks like the new Stihl 650 is closer to the 385 than the 460 is and I would rather step up than down. It's my first saw too. Any thoughts on which way I should go? I'm likely run into some big stumps.
