Good post there 3 alarm. I am fortunate enough to have a lifetime supply of replacement cogs and bodies for what is arguably the best freewheel ever made (Dura Ace MF-7400) and the tools to disassemble and replace cogs. These units are very long lived. HOWEVER - I've done an A/B comparison of the DA freewheel and current issue chinese made Shimano freewheel - the kind you can find on ebay for under 20 bucks - and I gotta say that they are almost indistinguishable from a shifting / performance standpoint.
But I do take your point - that good quality freewheels in desireable ratios are bringing silly money on ebay.
Hopefully we won't need to resort to cryogenics or plasma cutters to keep our old freewheels on the road.
