I'm thinking about getting a Powerbook with a superdrive and I might want to back up my DVDs. Thus, I was considering buying an external DVD-ROM drive so that I don't have to make a disk image and burn that to DVD. I want something cheap and reliable. Does anyone have any suggestions? Alternately, I haven't done much with making disk images and then burning to disc...Is it as much of a pain as it sounds like it is? Or is it worth the saved bucks to handle the minor inconvenience.
