All I will be cutting is firewood...Oak and some Hickory. At the most 15 to 18 inch stuff but that is rare. Thanks
You may be quite happy with an MS250. Nice light powerful saw. Stihl verses Husky verses Dolmar verses...? They all have a saw that will suit you. Irrespective of features/models, and after removal of religion, it comes down to how comfortable you are with the dealer support in your area. Some users are happy with no support, others not. Don't get tied up with air filtration and anti-vibe and... none of these really make much difference in the end for the type of work you are doing. Clean your air filter as required (good reason to check "under the hood" now and then), and you'll be happy.
My opinion on the MS310... Way over priced for what it is. It is after all just a slightly bigger bore MS290.... so if you want this size/weight, get the MS290 with and 18 inch bar and save a few $. 10s of thousands of very happy purchasers of the 290's and 250's out there.
Me? I'd get an MS260 if I was just doing firewood, and hand it off to my grandchildren when I'm too old to work (first I need grandchildren, but..), but you'll pay more for it up front. If I didn't have the $$, the MS250 would work just fine.
One way to deal with the Stihl "choice" is just buy one, use it for a week, and if you don't like it, take it back under their "Satisfaction Guarantee" for refund or exchange. You dealer or Stihls' web site has the details. Husky apparently has a similar program but I don't know the details.
