Actually, I would love to collect some opinions about the necessity of
a  non-frost-free freezer for enzyme storage (Defrosting is a real pain
in the neck).  We now store all our enzymes in insulated boxes (e.g.
Stratacoolers) in the freezer anyway, just to minimize temp fluctuations
when the door is open, etc.  Wouldn't this be enough protection against
the temp changes during the defrost cycle of a frost-free freezer - or
is there another reason for not using frost-free freezers?
