Somebody's talking crap here & it ain't the tree!
390 will do everything you want. A 9010 would also but the av isn't as smooth.
The first time I ran a PS-9000 I was actually quite surprised with the grunt. It is a heavy thing though, like a slightly smaller 880/3120.
I shouldn't have been too surprised with the power though as almost all of the older Dolmars/ Sachs Dolmars seem to have modern type power, just lacking on other more modern features.
The one I have in the shed was owned by possibly the biggest knuckle dragger on earth. It basically needed a full rebuild but running like a new one now. Nice saw but owning 7900's and a ported 390XP (+ 3120 if needed) I doubt I'd ever pull it out the shed to run it. Tough old saws but nothing special.
The owner is meant to pick it up this weekend - I've had it for over 18 months.
