(Heh, contact me when you want to buy - I will probably still have
my KS-4 available, M-, $1400 ;-) The address of the (tiny) factory
is: Ken-Lab, Inc., Old Lyme, Connecticut 06371 (203-434-1619)
They are very nice to deal with, and check-ups and servicing are
done promptly, and at low prices. BTW, the specs show the KS-6 to
be slightly larger than the KS-4, and MUCH heavier. Also, in my
original post, I forgot to mention that the gyro is at its best
with physically short and light equipment, and does little for long,
fast, heavy teles (too much mass and lever arm for the gyro to work against - great with mirrors, though). Also, if the gyro is moved
too fast, the gyro action will suddenly cease, making the camera
jerk (gyro action is immediately restored when the internal
suspension springs can move the gyros away from their stops).
These are very useful devices for many types of photography (that
I no longer do enough of to justify the cost), but they are not
exactly a "legless tripod". They do help a lot where it is useful
to go hand-held (they can speed up a lot of shooting, not having to
place a tripod for each photo [or in locations where tripods are
awkward because of water, terrain, furniture, etc. being in the way]),
or where the shooting location is moving (ladder tops, planes, etc.),
but they only slow motion - they do not provide a sturdy, fixed
mount for attaching photo equipment. Used with understanding, they
are great!
Hope This Helps
