The story as it is:
Circa 2006, I buy a new Model M for cheap. Months later, I stop using it due to buying an iMac; they lack PS/2 ports and I didn't have a converter (still don't, or rather not one that works).
Skipping forwards to a few months ago, I thought mechanical keyswitches were another name for buckling springs. Remembering that the clicks were too loud, and the force required to press a key was too great, I decided that I respected them for their engineering, but wouldn't want to use one. A few months ago, I read
the HotHardware article and watched the accompanying video, and was enlightened. I decided I'd like one!
A few days ago, I started browsing around for them. About two days ago, I hit on my first geekhack link. Yesterday, I became addicted.
I have narrowed it down to three contenders: the
Filco Majestouch Tenkeyless Tactile Touch, the
Filco Majestouch Tenkeyless Tactile Click Otaku, and the
Realforce 87U (the Happy Hacking Keyboard's position of modifier keys is unacceptable to me; I do not swap the caps lock and control key).
For the non-Otaku Filco, I'd buy a set of blank replacement keycaps. Can anyone confirm that all the bottom-row modifiers have the same size, so that I could buy a set (in the case of the Otaku; another, otherwise) and rid myself of that horrible orb?
I know I've given scant information, but does anyone have any suggestions?

P.S. In case anyone doesn't know, you can turn off the highly-irritating WYSIWYG editor
here; search for "Message Editor Interface".
