024 was not a bad saw. I picked up an 024AV a couple years. It runs good, and now my dad has it up in MD so I could keep the 025(i have lots of chains & multiple bars for it). Sorry to hear about yours.
The MS290 is the best selling stihl saw. Yes, it is heavy, but it's a solid, dependable workhorse. I'd rather use my 025, it's lighter & w/ a 16" bar, it's a cuttin' MOFO! I also have an MS361. Got it for free, because the cylinder was trashed. I rebuilt it, and it runs good. The pro saws are awesome to run, as their handles are all spring mounted to reduce vibration & really cut down on user fatigue. However, a 361 w/ a 20" bar is 610-620 new.
Before buying a used saw, jot down the model # & call your dealer about parts availability. If it's an MS series, parts are no problem, but parts for older saws can be a real ***** to get, if available. Seen lots of people that got a used saw at a garage sale or pawn shop that are unfixable or too expensive to fix. Worked on an 056AV a couple years ago. Need a coil, which was around $125 or so. But then it turns out you have to replace the flywheel because the coil is now different, and the flywheel was over $150.
