Emax

I have an emax HD and an emax I keyboard (with a brand-new floppy drive),
and am thinking of selling off the keyboard, as I don't need both.

I see many posts about the emaxII and the emaxSE...and wanted to know if
this is because no one uses the emax I's anymore.  Just wanted to see if
it's worthwhile listing the instrument on eBay [or here].  Thx.
