Ed:

We have also had poor results with Revco (beware that these units also
now come under other brand names, perhaps to escape their reputation).
We have had very good results with Forma Scientific's -86 degree units
(total of about 5 freezer years of completely problem-free operation).
Forma also has the most highly developed refrigerants from an ozone
depletion standpoint-- they are well ahead of the regulatory curve in
this regard.

Hope this is useful to you.
