Casio CZ-1 61-Key Synthesizer

Up for sale here is: the Casio CZ-1 synthesizer.  Plays great and sounds great.  It has a new battery inside, and I will include a power cord.  I am considering reasonable offers.  Please see photos carefully.  Here are some minor issues:

• There is typical cosmetic damage, like small scuffs, dings and/or scratches, but it's very clean for its age.  There is a cap missing for the volume slider.  The LCD contrast is somewhat weak but still readable (common on the CZ-1, it might have always been this way).
• The C4 key plays and "feels" normal, but sits slightly lower than the rest.  I know there is some small type of damage to the key because It can be "flicked" upwards more than others.  (It is simple for a technician to replace a key, if it bothers you cosmetically.)
• I have not tested the Cartridge function because I don't have one.  
  
• FYI the Chorus function is somewhat hissy, and this is a common feature of 80's synths using analog chorus chips (Juno 106, etc.).

I am only shipping this within the continental US, signature required.  I'm selling this "As-is."  Please do your research online (Youtube, etc.) and make sure this is an item you really want before purchasing or making an offer.
