Jim, which of the filters that HSC carries would you recommend as "a REALLY 
GOOD RF filter"?

BTW, perhaps I'm just lucky, but when we put Kichler Xenon lights in our 
kitchen remodeling I was worried about noise from the switching power 
supplies.  In 2 years we have had two power supples fail (immediately 
replaced by Kichler at no charge, so they must know there's a durability 
problem), but no discernable noise at all.  Perhaps it helps that my 
antennas are 200 feet from the house, or maybe it is something in the 
design of these power units.
