Ive run a lot of saws and ou didnt mention it, but, my 390 w/a 20" bar has been the most reliable saw Ive owned. I take it up in trees, cut all day, beat the heck out of it....plenty of power (with a 20" bar), light, and very very reliable. But, needing more to run bigger bars I bought an MS460 a few months back....AMAZING saw. Wompin power, awesome power to weight ratio and sounds great! I dont think Ill ever need more than my arbor saw, my 390 and my MS460.
