Tascam is great, I used to use them when I when I ran audio for theater/musicals. I however have not worked with CD-Rs from them. You can see that it's a standard CD-R drive capable of the same discs you drop in your Mac. Keep in mind that if you're recording yourself, don't get a unit with SCMS (serial copy managment system I think) because they won't let you make copies of your copies. Tascam should not have this, but someone like Pioneer would.
Personally, I would recommend that you use a Mac with a nice audio card, then burn your CDs from the Mac. There could be no loss in audio fidelity at all. In fact, you can even record at higher fidelity than CD-Audio supports.
With the two new high-res audio devices out there (computers, DVD-Audio, SACD), it would be a shame to degrade to CD quality when recording.
