I found a Dolmar 7900 that was new 6 months ago but I think they have been discontinued for some time now.  The new model is a 7910 that has been detuned thanks to the EPA requirements.  I've read that it's not too hard to modify the muffler to get more power out of it.  I don't have info on the 7910 but the 7900 is a 80cc 6.3hp saw.  There's a couple of things I don't care for, the oil cap is hard to remove and the kill switch isn't in an ergonomic place but the power is great.  I have plenty of red maples up to about 30" and had been using the 357xp (which worked well) with a 20" bar.  Now anything over 16" I don't think twice.  It'll cut through a 24" maple in 10 to 12 seconds.  I can't remember the weight though.
