Wow, this is really cool. I'd be interested as well...I'm assuming the expense is more labor than parts...do you have a ballpark?
my price guide:
http://16bitgamer.forumot...dding-service-price-guideSo you're paying for all shipping, buying me the appropriate donor cart, paying me 100$ to build and test the thing, then paying whatever shipping costs to ship it to you. I have some new printed labels sitting around for starfox 1 and 2, I can add a new label for 15$ extra.
