If you can find a NOS Plextor (712, 716, 755, 760, PlexWriter - uh... There may be one or two others), you're golden. If not, really any quality drive is going to do you reasonably well. Not that I wouldn't still recommend DDP for use as a production master for CD replication... But if you have to use a CD-R, get a good quality drive and burn away.
When I found out that they weren't making them anymore, I started buying them up as I found them. I still have one or two 755's in the factory packaging.
They're not for sale... But I can tell you that it's a very, very rare occasion that I'm actually asked to create physical discs anymore. People finally (re)discovered DDP (again). Granted, DDP used to be a PITA and the real bummer is that the client wasn't able to audition the DDP. Over the past several years, that's all changed -- No more Exabyte tape, no more $K's in hardware and software to load it back in. Issa wonderful thing. Hell, Tayio Yuden doesn't even *make* CD-R's anymore.
[EDIT] The drive above would probably do you fine. Write at around 25-ish% of the drive's top rated speed (in this case, 12x for CD-R would be ideal, but anywhere from 8-16x would probably give you a quality render). Turn off any "burn-proof" type stuff -- (1) it'll take the disc out of spec if it kicks in and (2) if the system can't handle a 12x render of 1411 kbps, you've got bigger issues than the drive.
