IMHO, if your life and well-being depend on owning an M70, and you have the money, why NOT spend $500 + $55 shipping on this one (or more, since the next bidder will have to top the current high bidder's [secret] maximum bid)?
Looks pretty nice to me, and, judging from the description (and assuming the packing is done right [which you can never predict]), it should bring you the happiness you crave. Minty fresh M70's are very hard to find, and will only get harder as the years go by. Besides, if you change your mind (or start collecting something else, like this seller says he's doing), chances are you could sell it and get your full purchase price back.
But if you're just a casual buyer and/or you can't afford to spend at least $555 (or pride yourself on getting low-cost "deals"), then this one won't be for you.
It's all how you look at it.
