Matt and Marcus;
two weeks ago I held a new version of the old KISC in my hands. It is not
out yet because it is going through UL. It should be out around the first
of the year. Cost less than half of first model.

The new unit is supposed to run 20 feet per satalite trans (one main
controller can run several sats)

It was reasonably quiet

The units that were working on the first system were done to "regular neon"
specs with 100% neon and a very small amount (but not a critical amount) of Hg.

The one on the outside of the MOMA building has been running for 3 years.
