All,
See
http://wilcoxengineering.com/projects/amateur-projects/44-ultimatic-keyer
for photos and a summary of the build.
Seems like the project was successful getting me close to what I was
looking for. Not exactly, but close enough.
Thanks for the advice!

All,
Thanks for the leads and advice. I finally selected the K1EL K12-battery
keyer. http://k1el.tripod.com/K12.html for a modest $17.
From the datasheet, it appears to have not only ultimatic, but
dah-override. When I get it built, I'll find out for sure how it'll work
for me.
Stay tuned ...

Alan,
That places you in my chronological age range - yes, I have my 50 year
pin from ARRL too!
I believe you are referring to "Ultimatic" keying - the paddle that was
last operated is the one that takes precedence - none of the "idiotic"
alternating dots and dashes (which to me is confusing).

Hello,
Fifty years ago I designed and built a tube keyer to replace my
Vibroplex. Then a transistor keyer. All this before the iambic keyers
came along ...
Left paddle = dots
Right = dashes
Squeeze both paddles = dashes only.
The technique I developed was to
1. Always squeeze _both_ keys for d
