Got a Sanyo M W717F today for $20.

It has:
-3 band graphic equalizer (100 Hz/1 kHz/10 kHz)
-2 cassette decks
-4 speaker system ( woofer and tweeter)
-high speed dubbing and beat cancel
-AM/FM radio
-headphone and mic jacks

Here's a link to the user manual:

The M W717F is quite similar to the M W717L, except the M W717F does not have the CD/Line In jack or fine tuning knob.
