It actually went for $29,600, and even though I am an Astro-Physics fan myself, is way too much money for that scope!
As a comparison here is a link to a scope of the same design with more aperture, just as much heritage, and which sold new for ten times the price when new (over $100K for the OTA alone, instead of $10K for the AP)
Questar 12" Mak with questar mount
Granted the questar was sold in 2006, but I think the comparison is still valid!! (the questar sold for $19,000 incase you don't have an account to see the sell price)
