[SML] Ultrasonic low fog machines....

[Jon Ares]

Yeah, I saw that liquid nitrogen system at LDI back in the early 90s
(about the last time I've been able to go) - very, very impressive,
but very, very expensive, as I recall. And/or, it was prohibitively
expensive to get the liquid nitrogen and necessary apparati in my neck
of the woods.

The dry ice method is a PITA here, due to very few suppliers, and the
need to get it every freakin' day, due to storage challenges. And now
that my business office has said "no more credit cards, we're going
back to 1974 and only issuing POs to Approved Vendors" - daily trips
to the ice cream shop or the one grocery store that (sometimes)
carries dry ice is basically out of the question.
