Not in for the contest but I probably own about 2-3 dozen keyboards, have sold a dozen others on ebay, have given away a half-dozen to friends, have donated at least 2 dozen that were junk to charity, and have probably spent at least $1K in total and recouped maybe $300.
Currently I have about 6-8 Model Ms, a Model F AT, about 3 working Model F-122s, a Chicony KB-5181, about 3 Dell AT-101s/101Ws, an AEK2, and around a dozen various good rubber domes (if anybody wants a good used Dell QuietKey, Compaq SK-2800, or IBM KB-8923 for something like $10 + shipping, let me know).
I have owned and sold a Leopold full-size blues, Cherry brown POS, a few Apple Keyboards and Extendeds with Alps, a couple of Chicony 5181s, a couple of Northgate Omnikeys, and I went through about 4 F ATs until I got one I really liked.
I also have several Model Ms and M-122 carcasses laying around.
Kind of disgusting, really.
I want nice 2 full-size Filcos or WASDs with reds and browns, which I will o-ring, but no hurry there.
