Cheap Back-up Solution

Hey there. Currently i do back up my data. I'm running a mac pro with two 750 GB hard drives and use superduper to make the second one a bootable back up. I do a lot of graphic design, audio/video work, 3d animation, and photography and there for have large amounts of data that are very precious to me. I feel safer now that i have this back up but if something happens like a fire or robbery, i'm at a pretty big loss if anything happens directly to my computer. I'm looking for an offsite backup solution. I know some keep second drives at their office...but i'm a student and my room is my office. Can anybody help? thanks!
