I just mine back from the Professor and have decided to part with it. Original owner.
Why??? Aren't you happy with the repair and calibration? Or just want to sell for the money? What service did you get?
It's been totally refurbished by the Professor. I just don't see myself using it , so I would pass it on to someone who would enjoy it.
It sold for that amount. I will dig into my watch list and try to pull up the ad for you. Why say it is absurd? They went for 600$ back in the 80s and that money today has to at least be double.$1200.00 for a PX-3 parts unit is absurd, did it sell for that or was he asking that much. I never look at the asking prices, I look at the sold listings.

Put up an ad on US Audiomart, it is free to sell there. No commission taken out of your sale. Also Craigslist, but then you have to deal with possible weirdos. But on Ebay you would have protection to get your money. Why not ship? If you sent it to Alan in Florida then you could ship the same way anywhere. Why limit the area to sell to. I used to be paranoid on the shipping but using the wardrobe box from Home Depot cut down to the proper size with thick foam padding it made it to Florida and back quite safely. Many people want a nice linear tracking table, less distortion than pivoting. And fully serviced by Alan should get you sold in no time. Post a pic if you can.I'd let go for $1000 picked up.
Well, you said it was sold for parts so I was expecting to see a parts machine. That was a pristine PX-3 in the box with all accessories. I suspect that it was used however or all the parts would have been in bags, not loose in the packaging. Stating it was found in a Stereo/TV shop does raise a few questions though, why was it there? Seller did no testing, always raises a flag. So yes, $1200.00 in my opinion is to much for that machine.
If yours is in pristine shape I'd say it could be worth $1200.00 to the right person, maybe more. The service done on it will help the value a lot.
