Well, after lots of internet research, I think I have narrowed the choices down a bit.
Leading contender:
Dolmar 420 at $265 delivered via ebay or $330 locally
Also considering:
Dolmar 350 at $250
Husqvarna 440e at $289
Stihl MS180cbe at $230 and MS210cbe at $290
Echo cs370 at $265
From what I have read these are all excellent 14 or 16" saws with many happy owners. I'm sure I'd be happy with any of them. They are all fairly lightweight (at about or under 10lbs) so should be good for cutting up brush and delimbing trees.
I'm leaning towards the Dolmar 420 due to the magnesium construction and "prosumer" rating while the others at similar price points are more clearly fine consumer grade saws. Against the Dolmar is the potential for service hassles though I did finally discover there is a dealer in Eastern MA. I am unimpressed with the Dolmar USA operation though. Their website dealer locator is broken and a phone call to headquarters to find a local dealer went to an answering machine. I get the impression they have a just as good a dealer network as Kioti does.:laughing:

Still, I am used to that by now and the combo of internet and UPS is something I have gotten quite comfortable with for service.
Now I need to decide whether to buy one sight unseen via internet based on reputation or whether to dedicate next weekend to visiting dealers.
Any others I should think about in this price/performance range?
