I got some extra money this week so I was thinking the Dreamcast needed something new plugged in. :D

I have a VGA box already :D
What accessory works with the most games? What one is worth the money?
I'm thinking The light gun, keyboard and mouse, the Microphone, or fishing rod.
I know there all worth the money but I'm not a collector I'm a gamer.


And any comments about the 4X memory cards? Are they reliable? Am I better off getting 4 VMU's?


Just looking for suggestions,
thanks for your time friends
