Value of Technics SE-A3Mk2?

I have a near-perfect Technics SE-A3Mk2 amplifier that I'd like to sell...but I'm having trouble determining a realistic value.  Cosmetically, it's not 100% perfect...I'd say 95% as there is a minor mar on the right panel.  Functionally, it is 100% and, FWIW, I have the original box, terminal cover, and manual.

I see on eBay a few listings from +/-$3000 for units with obvious cosmetic issues all the way to $6,400 for one that is advertised as "near mint."  That's a pretty broad range.

What do you guys think?
