Someone I know has one of these in what appears to be really good-to-mint condition. It's basically the set I want the least, but I still really want a CIB NES set. What do you guys think it's worth? (Including shipping I suppose). I'm thinking I'd like to pay ~$35 for it. Is that too low? He doesn't know what to ask for it, and I have no idea what to offer. I'm not going to buy it unless I get a really good deal, but I'm not trying to lowball either.
