KEMs were always less than great, I was always pissed off that I was outvoted on the NZ Film Unit's purchase of several (the guy who signed the cheque was a mate of the distributor) so we ended up with KEMs rather than the better in every way Steenbecks.
Shame it's in Sydney, Patrick Monahan who is an editor in Auckland was a KEM sorta guy and a collector. I don't have a contact for him any more.
My preference was Moviolas.
