Burnt up? Did ya throw it in the boiler by accident?...lol. Seriously though, you sure the 026 is no good anymore? Possible rebuild? To your question now, MS362, but I have one so I am biased. It is a very smooth saw, has quite a bit of grunt on the bottom and top end, and mine sips the fuel....no mods. I had a 361 and liked it ran it for 2 years but now that I have run my 362 for the past couple years I thinks I like it even more than the 361. It wore a 25" ES bar when purchased, it will pull it okay but I have a 20" that it likes more. The 362 does weigh about 12ozs more than the 361, not noticable to me. The 391 weighs over 2 pounds more than your 361, that is going to be noticable. If you are not worried about that much weight then skip the 391 and go for a 441, about the same weight as the 391 and just so much more of a saw in everyway. Good luck.
