I am considering buying a used GE Monogram Refrigerator, (42" side by
side, worth lots when working) but it has a known bad compressor and
likely a Freon leak.

What would be best case to worst case estimate range for these repairs.

Example : 300 - 700

I would like several people to respond and that will give me a really
good feel of my total investment needed to get this refrigerator
working.

Thanks,
Tom
