One of the earliest nes sets with the Zapper and the R.O.B. accessory. I'm not sure if it came with any games.

This is the Power Set which included the Zapper and the Power Pad (that big floormat thing on the box and a multicart with Smb1 Duck Hunt and World Class Track Meet.

This is the Action Set which came with the Zapper and the Smb1 / Duck Hunt Cart. This is the nes set that I have and is probably the most common

This is the Challenge Set which did not come with the Zapper : ( but it did come with Super Mario Bros. 3 which kind of made up for it : )

This is the New Style Nes Control Deck. This one didn't come with any games. It looks pretty cool but all I really want is one of the dogbone shaped controllers.
