If you can wait for the 2011 version to drop before picking it up, then I highly recommend the 2011 version over the older one.
Newer version supports videos, pictures, audio, Math clues, has a better editor, uses standard flash drives to load/save games, updated intro/think music/etc, 'fraction of a second' lockout on buzzers, answer LCD on the Host remote, comes in a nice case. The 2011 version is Classroom Jeopardy! done right. (Minus the pesky randomly-assigned DDs, but you can 'force' a DD and then it removes one of the 'random' ones).
This is still a fantastic deal.
