The hardest part of building the CMOS III keyer is finding memory buttons
with a really good 'feel', and I've found them, for about $1.50 each,
including switch caps. Contact me if you're interested.
If you're not a builder, then consider the LogiKey, which comes to you
pre-assembled for $130. This keyer runs on a single 9V battery, but I don't
have battery life info.
I agree that the switches used are less than perfect. Pay a little more and
get excellent tactility. Check out the MEC switches at SOLICO´s web-site.
MULTIMEC 3F series with caps of your choice is pretty close to perfection !
