I'm pretty sure this is a good deal, though it's hard to tell sometimes with Japanese games.
Play-Asia has a temporary price drop to $39.90 on the Dance Dance Revolution with Mario (GC) bundle. They say the list is $69.90. yesasia.com has it for $79.99, and lik-sang doesn't have it.

You'd need a Japanese GameCube, Freeloader disc, or some other way to play Japanese games.
