I would jump on the potential third one if it showed up within reasonable driving distance from me. These are awesome refrigerators and are a great reflection of how over-the-top Sears could get with its top of the line house brand models.
I don't recall if I asked this about the other one that was posted here recently, but would the freezer be a true zero degree type like on a GE Combination from the same period? Any chance the freezer would have a drain for easy defrosting?
