NES are not even close to rare...if anything you can usually find some average guy who will sell it to you for like $3 since near about everyone had one. Atari stuff is pretty easy to come by as well, everyone pretty much had one of those too. Forget what eBay says, I see Atari's with a huge lot of about 20-40 games for $15 at the most all the time at yard sales and flea markets.
