GNSC PASI Units?


Have any of you had personal experience with Great Northern Sound's PASI devices?

I would like to buy the PASI. However I contacted the Great Northern Sound three times by email and I never got a reply. Are they still in business? I agree with Rja on using the Bybee filters, they actually disimproved my system.
