Three saws in current rotation:
Stihl 039 (391 is the current version). Good saw, consumer mid-grade so it's heavy for the power, which you'll only notice if you also have pro saws to grab instead
Bought it when I bought the house.
Stihl 360 (362 is the current version). Great saw, bought it used so I'd have a backup saw.
As a minimum, buy a second bar and a couple spare chains. When you pinch your bar, you can take off the powerhead (as long as it has an inboard clutch which I think all Stihls and most Huskys do), and use the other bar to finish the job.
When you can, buy a spare saw in case your primary one dies in the middle of making the felling cuts -- you don't want to leave a dangerous half-cut tree standing in public areas.
Husky 372XP has migrated into my collection, it's almost unfair in a hot knife through butter way to cut firewood with it.
I used to have a Stihl 024AV (I guess a 260 is the closest current version). I bought that used as a lightweight limbing/brush saw. If I had bought it before the 360, it would've been fine as a backup saw to the 039 as well. I will buy another used one day
If you told me I could only keep one, I'd keep the 372XP.
If you told me I could only buy one, but to pick out the best price/performance for my needs, it would be the MS-360.
