The 570 is not a bad saw IMO. Especially for the ~$600 pricetag. And the new makita/dolmar EPA 6400's like the makita 6421 came with a $100 jump in price. That makes the 570 one of the top contenders in the ~$600. About the only negative I see to it is the weight. But honestly, when I was cutting with my buddy and we swapped for a bit, I didnt notice much difference between the 6400 and the 570.
Not sure where the 365 runs, but I'd venture a guess @ $~700 range.
The only reason I keep comparing it to the 361 is simply because of price. To get a stihl of similar size/power to the 6400/570, you have to jump to the 441 to the tune of ~$200 more. Stihl doesnt really have a saw to compair to the 6400. Because for the same price, you get the smaller 361, and for $200 more, you get the bigger 441. But if you had $750-$800 to spend on a saw, why in the world would you not get a 7900:thumbsup:
