I agree, recordable CDs (CDR) are the way to go.. drives are getting cheaper (starting at about $200 for internal, and slightly more for external) and you can get 650 MB disks for as low as $.50 per disk.. by comparison, a 100 MB zip disk is around $10.. Also, just about everybody has a CD drive in their computer, which makes it easier to give files to others or share files with several computers. With zip, MO, or other specialized media, you have to have access to that particular drive to access the data, but you can read a CD from anywhere. CDRs are, however, more complicated to work with, so take that into consideration.
