You could also fire up a SUSE Studio VM and just run it over the web in
about ten minutes from the start time, all for free. The Test Drive
feature only gives you (last time I checked) an hour, but SLED is
basically an enterprise version of openSUSE (see similar thread there) and
after building the SLED image to your specs (including just the defaults)
you could probably then save it to a LiveCD and download, effectively
giving you the same LiveCD experience with SLED (or anything else in SUSE
Studio) as you have with openSUSE by default.

If you have a box you can always install and not buy... purchasing is
required for continued updates, not to download and try right now.

Good luck.
