Refurb'd NES's go for about $50 in a store. On ebay, about the same. With games? Hard to tell. If you sell it on ebay you'll make better money than selling via other means, i.e. garage sale.
Most people will want to know that the 72-pin connector is in working condition, which most aren't considering the system is old as fuck. That's the cause for the "blinking" syndrome.
Someone like myself could get a "broken" NES for $10 and fix it for free with a flathead, so the only thing I'd be interested in would be the games. Still, I'd need to see pics.
Your best bet is ebay. Put a reserve on your bid and you'll be fine. Or sell them all to me for $40.
