The Game & Watch is a great great reproduction that comes with a little display stand and a really nicely produced box.
It currently goes for about $35-$40 shipped, but once they stop producing them it'll probably go up in value long-term.
So, I vote for that.
I've heard that the hanafuda cards are really nice too.
