Aircraft Spark Plug Service - Still in business?

Several years ago, on the recommendation of folks from this group, I
sent a set of plugs to Aircraft Spark Plug Service in Van Nuys, CA.
The plugs came back looking like new, each in sealed tube with a new
gasket ready for installation. Well worth the cost considering how
long it would take me to clean, paint and test each one IMHO. I later
went to work at a shop with all of the equipment to easily clean my
own plugs so I didn't use ASPS anymore. Now I no longer have access
to plug cleaning equipment nor the time so I went to look ASPS up on
the Web and their site is gone. Their AD in Trade-A-Plane went away
some time between June and August. Does anyone know if these folks
are still in business? Has anyone sent plugs to them recently?
