There are two full sized Mario machines available.
The first is known quite simply, as Super Mario Bros..
It`s a really nifty machine, and quite an add to any game room.
For more info you can check its page at the Internet Pinball Database.
The second is know as Super Mario Bros: Mushroom World.
This one is actually meant for ticket play, but can be used for regular play as well. Adjustable legs too if you`re looking for a machine for your kids. (Note: great selling point for convincing the wife or partner).
Once again, more info at the IPDB.org
If those two are out of your price range, while not check out this item. It`s a nifty little tabletop, and a steal at only $9.00.
