I have one of the cheaper keyring ones, but most of them are very expensive, the cheapest are usually $70 and expensive ones can be up to $700.
I also have the five Game & Watch gallery games which were on the Gameboy, Gameboy Colour and Gameboy Advance. They are the cheapest way to enjoy 'game and watch' action.
They are:
Game Boy Gallery (Game Boy)
Game & Watch Gallery (Game Boy)
Game & Watch Gallery 2 (Game Boy Colour)
Game & Watch Gallery 3 (Game Boy Colour)
Game & Watch Gallery 4 (Game Boy Advance)
and also an exclusive game to the Club Nintendo members of Japan,
Game & Watch Collection (Nintendo DS)
