Here is my old S10. Dad used to a lot growing up. I had to replace one of the metal guide bars last year. Last summer it ran. Haven't started it this year. Has a freshly sharpened chain. All I know is thisthing is a tank. Heavy but gets the job done. I just picked up a new Stihl 271 and want to pass this along to whomever may want to clean it up and appreciate a little more. Not entirely sure what's it's worth but from what I understand there aren't many of them around anymore and would like to get a fair price for it but am willing to work with the right buyer! Is $150 unreasonable?
