This is what happens when you leave the shop unattended. They don't all blow up, or get busted handles, or need fuel lines. Dollar for dollar, they are fine. If I spend the $249 for a 250, I get a plastic saw I have to de-handle every month to clean out the oiler line. I get to buy a new air filter every time I try to clean one, I do get a dealer that will work on my saw, for a price, and I don't get affordable parts. What a husky brings and gives you, I don't know, but what these plastic Poulans give you is a working saw, and if you leaned any of the others out as much as these are, they would last as long you expect or think these do. Yeah, they vibrate. So did the old saws, so do a lot of the new ones. Any saw will go to hell in a basket in short order if it isn't taken care of. There are weak spots, as there is in all saws, as there has always been, and will be as long as God doesn't start to manufacture them. I never see them without spark. I can always find cheap, many times free parts, and they are not hard to figure out. The one you have is a good saw, I have a 3450, and love the saw. Hate the puddle of oil seemingly always under it, but it cuts wood as well as the 029 Super I had, and I could buy 6 of them (including what I needed to make it go) for what I sold my 029 for. And that dribbled a few times also.
The micros are praised here, never used one. Have worked on a few, and they have their quirks, like any little saw from back in the day. I have three or four of the plastic Poulans, way easier to work on, and will cut you a tankful of wood any time you are up to picking up one. Not a saw I would run all day, my hands would leave the job site before I would, but there are AV saws in the same set up. A Craftsman I recently came into does, and its smoother than my Wild Thing or the Woodshark or the P3314 or any of the three for sale at the shop.
As smooth as the traded in MS250? Pretty close, which says more about the Poulan than it does for the 250. Which would I buy? At the same price, the Stihl. I can get more in resale for it. But pay twice as much as the Poulan, no, not me. But many would, and most wouldn't have a solid reason other than its a Stihl.
