I've used both the stihl 017(older version of the 170) and 250. The Stihl 017 is a great LITTLE saw. I bought my 250, because Dad took the 017 back and I needed a bigger saw after katrina. I like both saws for what they are designed for. The 017 is usefull if you have small trees that you need to get rid of or have to clean up after storm that knocks down a bunch of limbs. If you were doing major clean-up, I would look at the larger of the consumer line from stihl. But, I would not hesitate to buy MS170. I have not used ECHO, Huskey or the others mentioned here, but I understand they are all good saws. My advice, go to a couple of dealers and see what is available. Pick up the saws mentioned, see how it feels, etc.
