Not sure how clearly to say this... if you want an NES classic, wait till next spring. Then you can get them for $60 all day long. Apparently the scalping is over, as are the bootlegs (maybe).
The scalping may not be over if Nintendo makes any changes to the box. If that happens, you'll probably see tons of "First Edition NES Classic" listings. Collectors could affect that too if they feel that they need both versions. I really hope the scalping is over though.
