There is no mylar version. Factory mylar was not used on games until the early 80's. It could be mylar applied during route years, but again, operators didn't have access to mylar as we know it. I recall my youth NIB Bally's (Mata Hari, EK were the first) being stripped of all playfield parts and book contact being applied. The Paragon I've had since new had two sheets of contact as the contact was not available in wider lengths. Under the contact was a very nice playfield with the exception of the sling area. These games were very well played.
CPR have the playfield in the pipeline. Backglass has been out for a while and plastics.
The eBay game is not worth more than $1500 in it's current state. The last eBay Paragon that I paid attention to was local to my area, complete, no wear and it was sold for around $1500.
I agree with Toads, it is a player's game. It is not part of the cliche "Slow Widebody" that it used these days. The artwork is stunning, and the game has enough going on to pull you back time and time again. It is the quintessential Bally from Pinball's Golden Age. It is my favorite game of all time. I play mine almost daily.
