I paid 2k recently for an LE with a basically perfect original playfield and a just OK cabinet with plenty of dings.
I love the size and look of it... also, the backboxes on the old Ballys are monsters and probably wouldn't be able to squeeze an original into my lineup. $1700 seems reasonable to the right buyer, display replacements are maybe $100... another $75 to replace all the drops or $20 for new decals... and the backglass is a nice original, mine was kind of beat and needed a replacement.
This one certainly has a nicer than average playfield, I'd presume most sold have various degrees of wear hence the lower average price of them.
Regardless, most prefer the original cabinet, so while the price is fine it'll take a minute to find the right buyer. I'd be biting if I didn't already have one, there's a ton of game here for the cost!
