I bought my Paragon game in 2004 for 400 dollars from a guy that was in the service and needed to move to California. The game isn't a great game (notice the price), but the game can be played and what it needs is a good restoration effort. Mostly, it needs the playfield artwork repainted, a good cleaning, and the game box needs to be repainted. I don't have pictures of the game yet since it's standing on end waiting its turn for a good restoration, but once I do get around to restoring it, I'll post plenty of before and after pictures.
Paragon is Bally's first electronic wide body game and also the first of their games to use inline drop targets. They made 9,120 games in June of 1979. The game features 4 flippers, 4 pop bumpers, 2 slingshots, one 4-in-line set of drop targets, one 3-bank of drop targets, 3 kick-out holes, 2 standup targets, 4 star rollovers, 1 spinning target, and an upper right chicane lane awards lit features. The game was designed by Greg Kmiec with artwork by Paul Faris.
