I have had my Zip drive for almost 3 years and it has worked great.  Although the performance of the drive has been great I find that the media to be too expensive and much larger than the comparable LS120 drives.  Another suggestion is your buying this drive to use it for fast access to  your files, don't go with the parallel.  Instead go with the internal IDE  or the SCSI.  Both of these are at least twice as fast as a parallel drive.
