If you're using it for a mill you need a 660 or 880. Other that that a MS261 would be excellent for the work you describe. If you want something bigger that can handle a bar longer than 20", a MS462 would be an excellent choice.
Does it really need to be that big?
If so, I’m not ready for that yet.
You dont want to mill with a saw below 80cc IMO.
I had a 562xp. Great saw, but mine was an early one with some electronic issues. I believe they now have these issues sorted out.
Stihl is coming out with a new saw called the MS4000 which the specs on it look impressive. The also have a 5000 with impressive specs.
