i don't see fisher fading away, but there is redundancy in what they manufacture
as teknetics and fisher are almost a "dead nuts" match for each other in their top of the line models.i believe tekentics may be 'dropped" with fisher soldiering
on into the future.this move may be considered because of costs, and ftp's wanting to keep it made in the u.s.a.as you mentioned, they are into other products as well so i don't see them going "belly up" anytime soon.
"smart money" says they are developing something in "skunk works",but just not ready for a "reveal"
as for "sweet home" i think they are going to ''surprise" us at some point, just don't know when! from a sentimental perspective,i really don't want to see them "croak!"..on to the next!

(h.h.!)
