I have an old Plextor 4Plex that I got when it first came out about 5 years ago and its still working the same way it did from when I forst got it... you might want to try the Plextor brand but you're going to need a SCSI Card. Their drives are also quite expensive and with the stroke of uck you've had with your drives, it isn't likely that you'll take that chance.
If it's any consolation, CD-ROM Drives are always the first thing to break when buying a new PC... soon, they'll be disposable.
