I remember at one point most decent bike shops had these massive boards with all sorts of Maillard cogs to build anything custom and replace anything worn.

ISTR that we had 3 boards. A blue one (Maillard) and a white one (Suntour) in the shop and another on a wall in the workshop with Regina Extra and Oro on it.
Availability (or lack of) of replacement cogs for cassettes is yet another thing that bugs me these days. I spend a good 75% of my time riding the same cog (and I suspect most other people do the same) but when wear rears it's head I've either got to hunt to find the part I need or fit an entire new cassette.
