You may not even have to spend that much. Look on Ebay for a vintage Sansui tuner like the TU-717, TU-719, or le creme de le creme, the TU X1. These will smoke any tuner out today less than $2K. I have the TU-717, bought it for $150 on Ebay, it was an upgrade from my Magnum Dynalab FT-101A tuner. Not only does it pull in more stations, but it's warmer and sweeter musically. The late 70's and early 80's was the golden age for tuners. I favor the Sansui models, but Kenwood and Pioneer also had some very good tuners.
