Lacie comes with Toast Lite, but you may want to get Titanium 5.2, iMax, if you are looking to do something more than CD-Rs and CD-RWs.
I agree with Lacie on this. The only legit downside I can think of from using two different CD-RWs (16x10x40, which I accidently busted, and now my father's 24x10x40 muhahahahaha 😀) is the noise the CD-RW makes when it's on. It isn't too bad once you get used to it, but I'd rather deal with noise than a crap CD-RW. 😎
