I've been messing with it for just as long, but still...ugh. It
is just a pain to deal with, IMO.
Ugh. ;)

I wouldn't mind playing with some, if I had the
appropriate
transformer and such to drive them with. Used to be that you
could get a
transformer with a nominal 125VAC output fairly easily, I
haven't looked
to see if they're out there these days.
Ugh, line power. Much safer to power stuff from low-voltage DC. Try this
step-up circuit; it is based on an MC34063 app note design
which I've tuned a bit and adapted for current component
availability:

It's cheap, easy to build, and powers Nixies nicely.
Yeah, but a transformer, bridge rectifier, and filter cap is
*so* much
simpler.
