The refurb sounds good to me but the question is if they can refurb they must have a way to deal with a NLA part, or they can take one from an otherwise dead unit. Maybe talk to the people who do the refurbs and offer a "finders fee."

Also, the the drain is physically there then I think it can be rebuilt. With that kind of replacement cost you can afford to have parts made if necessary. I agree that the drain likely is built from outside vendors parts. Specifically any coil would be available from McMaster or Digikey.

Check on appliance forums. Some are professional, at least one is. The washer sounds incredible so don't give up on this. You can probably get a temporary replacement for a couple bills used. I've been using a Kitchenaid take out since 2010.
