Dear Lucie

We're buying a new -80 freezer soon.  The word I got from those with 
experience is:

So-Low is not so good.

REVCO (the we are replacing) once was good but has declined in quality 
(along with GM et al, apparently)

Forma is the one we're buying.  NOTE: the high end model requires 220 V. 
Ours is the smaller (23 cu ft) 110 V model.
