I would say that the AMI C is in a different leauge compared to the E or Fmodel. Like you mentioned, it's got a more classic era jukebox look to it and it's a bit more desirable that the E or F.
I've got a lady locally that has a AMI E that she is trying to sell for $2650 with cracked lower plastics! I talked to her on the phone earlier this week and she seemed like she knew that her price was just a *little* high
Yeah, the E's & F's are definitely coming out of the woodwork.
