I wanted to thank all of you for your advice...
got the Ranco off EBay, and the wiring was not that big a deal ..
Connected the 15 cu ft freezer, and set it to 42 ... I was amazed how fast the freezer came down ... holding steady with 3 degree differential (is that enough ?)
I am lagering a clone brew called Road Dog Ale, which calls for 42 deg for 3 weeks in secondary. It is nice to know that the temp will be steady.
Looks like lagering is now part of my vocbulary ...
