I wouldn't take it too seriously. Looks like the guy has no clue what its worth and just put a high number up. Its OBO. Im sure he will get a few 2-400 offers on it if its working.
Yeah, he even said it was in a garage and no one wanted it, so he took it. He knows it's not worth much but probably picked the high asking price just to get attention. Smarter guy than anyone seems to think!
I love Rescue Raider, but yeah this guy's a total dahoyey. Sente stuff is cool, but I sold a full working Rescue Raider kit with Monroe sticks for 350 dollars. I can't see this being worth more than 500 dollars.
