The best one is the SANYO one. Never failed in our labs and we have quite a
lot of them

of you posted that you also were interested in information on this subject.
I posed the question of "which -80s are best" to the building manager of the
facility I used to work at.  He's been the building manager there for quite
some time, and has seen a lot of freezers come and go.  I thought some of
you might find his comments helpful,so I've appended them below.  Please
note that neiter he nor I have any affiliation with any of the companies

>         You are correct when you note that I have bought a lot of So-Low
over the years.  What I like about So-Low is that the cabinets are very well
made.  We do not have the door/inner door problems with them that we do with
Revco.  Their refrigeration system is the same as Revco, pretty much, and
they are less expensive, on the order of $5,000.  The down side of the
So-Low is the fact that they are quite noisy.

about $8,000.  They are much quieter than any I have heard.  They also now
have a lower and upper OUTER doors so that when you open the freezer, you
are only opening one half of it.  This limits the frost build up and also, I
would think, the temperature fluctuations inside the box.  My -80 repairman
likes the refrigeration system design that they employ.  I do not yet have
adequate experience to forecast whether or not they will run longer between
compressor changes than the comparable So-Lows.  Ask me in about 3 or 4 more

said:  "the question is, not IF, but WHEN your -80 will fail".  Most upright
units run pretty well for about 5 years, and then need a compressor change
for about $1200.  Chest units do much better, but require enormous amounts
of floor space which no one really ever has.
