I think it take some more time before people are willing to pay $100 to refurb a broken MDD power supply when they can buy complete units for that amount. I have 3 dead MDD PS in my garage waiting for the day that it will be worth fixing rather then replacing them (I have 3 working MDD machines).
This is true as far as it goes. By that, I mean the difference is that when you buy a used MDD, you have NO idea where it's been or how hard / long it's been used. Your "new" replacement PSU may last years or weeks - it's a crapshoot. A newly refurbed PSU, on the other hand, is likely to last quite a while.
The other advantage, of course, is that you also get other parts to keep on the shelf as well, although after you've collected 2 or 3 extra motherboards and other stuff that is NOT prone to breakdowns, you're at the point where you're just running a junkyard.
…sez me…another hoarder with multiple MDDs, Cinema Displays, PowerBooks and a thousand or so miscellaneous small parts laying around…
