This link is the only machine I got searching for "ultrasonic
LUD-200B Drilling machine
It looks like the machine we used to have long ago, which was an
Imahashi - You can go to Imahashi, but they don't sell retail. That
price is about what they run, but you should definately shop around.
Rio Grande used to sell high-end, really expensive ones, like
$30,000 for the chip industry, but I don't see any reference to it -
it was actually a spin off of rio grande. The Imahashi's or similar,
are real nice machines for a moderate cost - As with all things,
you'll need to figure out how to use it - they're a little quirky, or
used to be.
