As far as I know its just a labelling device and they are exactly the same.
What to look for is what types of disks the drives can write to. They need to be able to write to + and - disks and some can write to DVD RAM disks as well which you may or may not want. Some drives can also do Lightscribe which is where, with special disks you can create an image on the disk to pretty it up.
So ignore the name of the drive and look at the specification and see what it will write to.
If you did get it wrong the simplist solution is to get an external CD writer. You can get internal ones but some are more differcult to fit than others.
What you want is a drive that can write to +R and -R disks and DVD RAM if you think you might want that (not interested in this myself as they are a bit pricey ) and if you want to create fancy patterns has lightscribe. Lightscribe disks are a bit more expensive than normal DVDs by the way and I also haven't used lightscribe as it doesn't interest me either.
If you have any doubts at all, post details of what you are considering and I'm sure someone will advise/assist you.
