coolness factor is probably higher with a complete power glove than with some buttons in a game boy. I may be wrong, but the buttons don't really stand out as being such a distinctive feature that people could instantly identify them when seen in a DMG.
If you have a power glove i will trade you 2 sets of grey buttons for double the coolness. I can even include a matching power switch and link port cover.
edit: please don't kill a power glove for the buttons.
rygD I don't own a power glove that was just one of my mind trips thank you for the offer thou, did you ever find the case?
