The big problem with recovery disks is there's really no way to make sure they burned properly other than to try to use them. And if you try to use them and find out one of the disks is bad, it's usually too late to do anything about it.
FWIW, I think once a computer is set up a System Image should be made. Maybe as soon as all Windows Updates are installed, SP1, IE9, and the anti-malware of choice. Then make a second image after all other optional programs are successfully installed. Then update that image weekly, nightly, or on whatever schedule is best for your needs. If and when your computer gets borked, use your latest system image to be back online in 30 minutes or less. The newer the system image the fewer updates you'll have to do.
