Condition,the dealer name on the plate & geography are a big factor on Time clocks.
I see em on swap tables around here asking 1K to $1500.
But after the show,the sellers usually come down to $750-$900 here for a clean one with a dealer plate after it doesn't sell.
Waynes Neon Clock repros all the parts for these for a total of $300-$350.
