Roger, I believe the machines have served well in the line of duty.  One
is ten years old, the other is 6 years old.  If you have slipped several
hundred slides daily on each machine for their life duration, they have
been real troopers for you.  They could probably be rebuilt with all new
O rings, rubber gaskets, new springs, etc., but the cost might easily
approach half or more towards a new one.  How about looking for a
secondary vendor to sell them to and buy new ones.  Or, most likely,
they have been depreciated out long ago (average life for depreciation
is generally 5 years with some rare items being 10 yrs while some corps
do a 3 yr depreciation) and you may wish to look at the scrap heap or
donation to some organization.  They would probably work for low volume
lab with adjustments, but not high volume in current condition.  Just
some points to consider.  sharon osborn
