For me, this whole thing stated with a €20 impulse buy:
"Lemme see if Google can tell me how to fix this thing ..<click, click> ... *vintage derailleur" <click> ...... What's a Bikeforums? <click, click> ...... <click> ... <click> ... Hahaha! ...... <click><click> .... Ow, that's nice ....."
Many more impulse buys and wasted hours followed.
You know what's even better than a 1984 Raleigh Competition 12?
Two Raleigh Competition 12's!
