I do have to agree on the time thing, I have less and less to spend screwing around with equipment that isn't reliable, and if I'm on a paying job, or helping my logging buddy out I need my stuff to work. Looking for parts for a 20 year old saw is out of the question. My time is far too valuable to screw around like that.
I understand that. I've only ever bought one saw new, my 066 that came as a package deal with my M5 Logosol mill.
Some of my free saws were from a logger friend , who like Yourself can't fool around with breakdowns. That's where I got my first free Stihl, a well used 038M. It just needed some cleanup/attention, ugly, but still runs great. This was 1998. I can still see the machine marks on the piston.
All the rest I've gotten free or nearly so and rebuilt/refurbished them myself, I like to think I do good work, > 30 year old Stihls.
Most I consider very reliable and I have a stock of NOS OEM consumables, some P/C sets, and parts carcasses for them all.
If they break I can fix them cheaply, and when they do fail, I have duplicates that run at each displacement: 009 and 020T, 026 X 2 and 028S, 036 X 2, 038M and 038S---> 038M conversions X 2, 066 and 056M.
If a 026 or 038 goes down I'll just grab another one.......
I currently have two more 026, not carcasses, that just need P/C work (have NOS pistons) , a 064 I need to fix ignition (@L34 adapter fix), and two 056Ms one needs ignition (@foggysail fix) the other an oiler (which I have). That is 5 more good saws in the wings.
I don't have $3000 into ALL the used saws and parts.
