Ok....I've had this for QUITE some time and I'm just not using it. I got it long ago and stashed it away just in case. It's a brand spanking new Power Base Convertor for the Genesis. Box is a little worn, but still in nice shape. The Power Base convertor is still brand new, in the original plastic inside. I haven't seen many of these around lately, and I just got a Pro Mega Master so I can play SMS games on my Genesis 2 and Genesis 3 and CDX, so I don't think I'll be needing the PBC. Anyone have any idea what a new one is worth these days?
