It nice to have someone ask a question with all the information I need to answer it.
The AIR-17 in Excellent and working condition is worth around $130. In pristine (Like New) it is worth around $150.
I can't recall Daisy ever having made one, but you may be thinking of the Crosman AIR17.
This model is no longer in production it was made between 1985-90. So finding one is not easy. You can try Craigslist or Gunsamerica on the web but it will take a while to find one. I recently saw one on Youtube. I have one if you are interested urnuts73@yahoo.com
