Adding a few categories:

1b. Players with (little or) No skill (or no time). They're not looking for CQ pins on the market, they just want a working game. Most can still fix basic things, change rubbers, fuses, check connections, send a board for repair... but prefer playing over trouble shooting. No interest in modding the game, except to correct design flaws (air balls, etc). They can live with an esthetic flaw... but can't stand a non working switch.

6. Hoarders. They simply can't resist getting more pins and end up renting a warehouse. They own multiple copies of the same pin. They hardly ever play. They justify their bahavior by rising prices - this is an investment (they tend to collect B/W)

I am in 1b.
