There is also a good pricing website that I use as a store owner:
http://videogames.pricecharting.com/console/virtual-boy?sort-by=name
It covers most things VB and has a graphical history or the relative prices as well so you can see the trends.

VN 101060460

That’s sweet. I am new to being a VB fan, but I’m loving every little thing I see.

Thanks for sharing.
