The D-70 is still relatively cheap compared to a Juno-106. You can find a broken one for $150 (screen missing) or a working one for $400. If you buy the hardware, you can sample yourself . This is the only way to get the full "Super LA" synthesis with the analog filter resonance (the D-70 had digital filters controlled by analog circuitry).
