Coolest looking vintage tuner.....

Pioneer 9500Mk II is a really nice tuner, I'd never part with mine

I have a Pioneer Elite F-93 tuner. Looks and sounds perfect IMHO.

I'd go with the Mitsubishi DA-F20. It looks great and is often considered one of the better sounding tuners ever made. You can usually pick one up used for around $100-200.

H.H. Scott equipment was always thought of as beautiful. I have an old tuner that I built as a kit stowed away in a closet because it is too nice to get rid of. "Good stuff", all of it!

IMHO looks should be secondary but I also like equipment that looks sexy and matches my other components. Take a look at the Accuphase T101 FM only tuners. They have the classic look still maintain there original value and sound great. They only come up occasionly on Gon I would grab one.
