I would definitely recommend it! The artwork on the tiles looks better for one thing, but there are also 84 tiles rather than 72. The configuration of features on the 12 extra tiles isn't anything you can't get elsewhere but there are certain tiles that can get you out of situations where you'd be completely trapped in the basic game!
I think that Z-Man are due to release this in the autumn and this should include the Gingerbread Man expansion too, so I'd wait until then before getting hold of it if you can.
