Looks like it might be unused...I don't see one bit of evidence of use.  Has some light wear from not being stored in a box, but you could probably buff it out.  So it's not mint, but it's darn nice.  Tested, and everything seems great.  I did not add water.  Guaranteed to work!  Comes with everything shown.  It looks like it missing the plastic reservoir for the back, but you could probably get one from the company.  Hard to beat the color.

If you live in L.A., I would do local pick-up so you could save the shipping fees.  BUT, if you choose this option, you would need to pay in cash upon pick-up.  You would be welcome to test the machine as long as you wanted.
