Years ago, I worked for a large equipment rental company. The ONLY chainsaws we rented were Stihls...
Left there to work for another large rental company, and guess what saws they rented... Husqvuarnas...
Like the other guys said, they are like Fords and Chevys...
Personally, I prefer the Stihl saws...
They don't have as much plastic crap on them...
But...
If I were only upgrading from an electric saw, to limb a few trees now and then, I'd spend 1/3rd as much, and buy a Craftsmen chainsaw from Sears...
I bought one 2 years ago for $149.00, and I've cut down and cut up at least 7 (60+ft) trees with it... One of which, was for a neighbor, and I charged him $150.00.
So my chainsaw essentially cost me nothing but my labor...
The Craftsmen saw will be cutting up another tree next weekend...
It runs like a clock...
Just my 2 cents....
