You're looking for a SCSI CD burner, right?
Why?
I know a lot of guys who are SCSI elitists, and who won't touch a lowly IDE drive (HD or CD), but the performance of IDE drives is now on par with most SCSI drives, and with a price that is nearly always much lower. Ten years ago, I nearly always used SCSI drives on the servers I built, but not on the desktops, because of the price differential. But now I nearly always use IDE drives, in all circumstances.
The only SCSI CD burners that I can find anywhere are professional CD duplicators, allowing you to duplicate 2, 4, 6, or more CDs at a time (
And they, of course, are rather expensive. You might also check out Panasonic and Plextor, as they are the only companies that I could find that had SCSI CD-R/RW drives in their product lists.
