Yeah, I thought about that. I've seen similar ideas before and was
hoping someone had seen something cleaner, or even  simpler.

I've been working with high voltages for years, I'm not worried about
zapping myself.

Those are almost what I need. If the both the price and available
output current were much lower, they'd be perfect.  In fact I have a
few old modules very similar to that in my junk box. Once you hit
100ma or so the circuit is usually complex enough to justify a small
traditional power supply. I would like to find modules like that for
about $5 that provided about 10ma.

This is closer to what I had in mind:
