Wow after seeing all of those, I'm torn. I really want to get it so I can play original KI. How much are those boards going for? Is it really just switching out the boards ? I heard you would have to switch out the HD's as well. Is that wrong? Is there any way to hook them both up so I can play each without physically switching the boards every time? Sorry for all the questions, I'm new to the JAMMA stuff.
