How much is that for ?
I would suggest that you try and get a "real" CDRW drive instead of a combo drive, as combo drives are not really very reliable. Perhaps you can exchange Microsoft Works 7.0 for a seperate CDRW drive, as you probably already have a copy of Microsoft Office or some other good Office Suite, or you can easily get Sun Star Office, which is free and very feature-rich.
(BTW, I have moved this to the right forum)
