dude, that sounds like an awesome score.
I'll add my two cents on this topic and agree with the consensus that you can't beat finding about anything in the wild. I mean, I found 2 2600's ( a jr. and a 4switch) for 7 bucks and there's a couple more left. I'm itching to get back there. I mean, if you been through a collecting drought and you see a joystick or just the back of a cart, you heart starts to race a little bit and your mind calculates a myriad possibilities. You just know it'll be quadrun or a proto, but then you pick it up and buy another copy of combat for 25 cents. It's all fun.
