Tape Backup

[chip33az at netscape.net]

Does anyone know of an inexpensive tape backup that works with Linux?  
Preferably external and USB.  Speed isn't important, but backups are.

I'm looking to backup my home "server" and using another drive just 
doesn't appeal to me.  I also don't want to use DVD's as it seems like I 
would be using about 10+.

I have about 50GB - 60GB of data to back up.

Thanks for any guidance.
