Trying to track down this short story about a father who dies but comes back to life as a robotic version of himself. There was this traveling salesman who sold the household on this process whereby the deceased person's mind was implanted into a lookalike robot. The robotic dad is delivered to the household and his young son doesn't want anything to do with it at first. The boy eventually moves away, leaving the robot dad behind. The robot just continues living at the old house (it was in a country setting). It was a bittersweet story and now I can’t remember the collection of short stories it was in!
I finally tracked this down, the story is 'The Resurrection Man's Legacy' by Dale Bailey. An excellent and haunting story from a collection by the same title. (“The Resurrection Man’s Legacy,” first published in The Magazine of Fantasy & Science Fiction, July 1995.)
