My initial impression of the 2150, upon opening it as a wedding gift, was that "so-so" was too kind. I was used to my grandpa's Partner 5000+. But that little Poulan did me right for, as I said, 15 years of light firewood cutting and general tree maintenance on our partially wooded property (mostly cutting up storm-damaged silver maples and bug-killed elms). I had to pull the limiter caps to keep it jetted right, and at some point I added a purple chain brake off a dead wild thing. Other than that, its upkeep over 15 years of regular use included fuel lines twice, one carb kit, one recoil spring and rope, one clutch drum/spur, and one muffler. Two bars. Various chains. Always ran 32:1 mix with whatever two-stroke oil was cheap/available. I think that is pretty good.
What made me decide to retire it was, the coil worked loose and grooved the flywheel, and it was about time for another fuel system tuneup, and the compression had gotten pretty low judging by feel on the pull rope. I found a Craftsman version, in gray, of it on CL for $25 that needed a bar but had good compression so the 2150 became the Craftsman's parts donor. The Craftsman is still my small-tree-and-fencework saw.
