Finally got to some hickory and black locust in my wood pile and decided to get a new saw. My sears saw isn't powerful enough, my Pioneer is but has no chainbrake and is heavy. I was thinking either the 390 or 361. The 390 is a bigger CC motor but the 361 is 0.1 hp more. Is it worth the $100 difference? Do these saws have as much power as my Farmsaw? I can get a good price on stihl so that's why I 'm leaning toward them.
