well emile
first off, i belive you got firewire on that puppy right?
second every cd burner that you get today has CDRW along with CDR.
and lastly if you want a simple CDR that you can just plug in, and will work with itunes right off the bat you are looking at spending about 150
i am a personal of Lacies harware, i picked up a 12X4X32 burner back in 2000 when i got my G4, i have since upgraded the drive in the FW case and she is still running strong with over 350 Cds burnt.
so
here is a recent drive that will work in itunes and the finder, and will only cost you 150 bucks
