As someone who has a low play Shadow it would take more then 5K to pry it from my hands. This one for sale does have a decal over the scantum area so I hesitate to call it pristine however the OP never made that claim and this does appear to be one of the nicer originals I have come across. The price police have no effect on pricing and if anything they help sell the machine with the constant free bumps and keeping the post at the top.
Why does it matter if the Shadow is selling for NIB prices? Some of these NIB games can't compare with the toys and mechs in Shadow and this has more to offer then a tie fighter on a spring. If Stern released this game today people would be wetting their pants.
