Nigel is right... You want that classic sound, then the price is higher.. Here's a good example. I was watching PBS the other day and one of my favorite shows came on which is "The Antiques Road Show", and someone had brought in a 1960's model Fender Tele. It wasn't in mint condition, and you'd be shocked at the auction price for it.. The guy borrowed like $150 from his parents in the 60's to buy it, and now he can get upwards of $9,000 for it at auction. Keyboards are like that too. Look at the old Roland Juno's, the Yamaha DX's, The old Moogs, ect..... Those babies in mint condition sell for a lot more than you'd expect them to.
