CT4, it may not be necessary to purchase a zip drive. The media will soon be done away with. They are already trying to phase out the the 100mb zip drive and disk.
I use what's called a jump drive. Some people call them flash drives--samething. Here are the advantages:
1. They are used like floppy disks. You can use them in any computer that has a USB port. Most newer computers have at least one.
2. They can be used on both PCs and Macs without having to reformat the disk.
3. They are small enough to fit in your pocket. I carry mine on a keychain.
4. They are available in any size starting a 56 megabytes.
5. The prices have really come down since the media first came out. Most store have sales every so often.

For archiving documents I think it's better to use a CD-R. They can be read in any computer, and they can't be accidentally overwritten.
