That's part of the problem..  I don't really have any idea what they're worth.  Make me an offer and we'll go from there.  

For trade right now what I need most is an ArcadeVGA or J-PAC, but may be interested in other stuff too.  I'm probably leaning more towards cash at this point unless you have one of those two items.  

I haven't gone through and verified that they all work, but I have verified a couple.  If we work out a deal I'll double check to make sure that you're getting a tested/verified working one.
Thanks for the interest,
