I eliminated the Stihl, as I spoke with 2 of my local dealers and both said "Yes, you will need to do a valve adjustment at some point". So it is off my list.....
After trying on both, I think the Husq is more comfortable, and the beast of a filter that is easy to change out give it a leg up in my opinion for my needs.
I will be buying on in the next 10 days as the leaves are starting to fall!
The Husky's have a back cooling system as well, and it works too.
Darryl has alreay posted a bunch of useful links for anyone here to read, but I will just say that I have ran both the Echo 770 and then the 570, and I bought the 570. It may have similar specs on paper, but it is a different story out in the field. It blows harder than the 770.

Not correct. Its right in all their manuals- 139 hours or as needed.
No one should be put off by the valve adjustment on the Stihl. It is a one time thing, and for many guys, it won't need to be done for a couple/few years. They recomment doing it at 139 hours, or as needed, meaning if the machine starts getting hard to start or running sluggishly.
