The MS311 is a good saw. Saws in this quality range are "landowner saws". Tend to be a bit heavier than pro saws, run lower rpms, have a narrower power band, and will need serviced sooner--but it's intial price is a fair amount less too.
I would recommend the 20 inch bar also, heavier but a longer reach and more versatile.
Not to make your choice more difficult, but consider the Husky 455 Rancher. Although 5cc smaller, it's lighter and rated for more power (a manufacturer's rating doesn't always tell the story though). Plus I think its less money.
I've used both, but not the current ones, and things change every couple years these days.
