Need 3.5" external drive for AIIc+

[ECZ5GEL@MVS.OAC.UCLA.EDU (gerardo llamas)]

     I need an external 3.5" drive for an Apple IIc+.  Most prices I've
seen are around the $300 range.  I need a less expensive one.  I will
buy used.  Or maybe you can direct me to a magazine that still carries
mail order services for the Apple II series.  Thanks in advance for any
help.
