>I bought a very good USB 60gb external hard drive for this very reason and have not regretted it. I have the image of 3 separate hard drives (separate systems) on it all the time and twice I have had to restore from the image due to hardware failure on one of the systems. It only took one time for me to make it a habit of having an image on a usb external device. I use Ghost 2003 and it has worked well for me. The USB external harddrive cost me 51.00 on ebay.

I still have my trusty DDS-3 DAT drive, but it's getting less use each week.
I also have images of very raw OS installs for each computer and OS - these will be re-imaged for base beta's - no more installs for that as well. The thing is, having more machines forces you to clean up your backup "strategy" - when I relied on a large disk with many consecutive zipped and named versions drawn from SSafe for unwired testing, I nearly never cleaned up properly, creating a mess. Now the redundancy is in hardware, the only task is to set up correct directories on each machine/mapping/OS-combination and let synching do it's magic. I am a firm believer in throwing hardware at problems <g>. Earlier attempts with movable drive bays were not so successful, but USB and FW support was for me the main thing that switched me over from my old and [t|c]rusty NT4. The best days are those when I just take the small case with the USB, a few spare cables, 2 screwdrivers and empty DVD's to the client. And in a few years that will be just an USB stick and 2 screwdrivers...
