Three years ago, there were THREE or FOUR Paragons on Ebay - Wotto's, one in Tasmania and two Melbourne based. One of those two was strictly a project. Late last year, a Dealer had TWO, one on eBay. They DO appear from time to time on eBay etc, but they rarely change hands once they are in a collection.
A project or rough machine would not be worth more than $700
A working / unshopped with good backglass and playfield $1000
Reconditioned / shopped $1800 - $2200
Restored $2700 +
I will never part with mine. Backglass and playfield is a 9/10. Cab is faded. I was offered $3500 by a collector 5 years ago (after I restored it).
If you are patient, you will find one on eBay. There is at least 1-2 per year sold on eBay. Not that rare ! But NEVER changes hands !
Edit - Found the link to Wotto's beast that sold on eBay for around $2200 - $2300.
