I don't know about the ebay prices you guys are qouting. I watched this one for several weeks back in the fall. The cheapest I saw it sell for was w/o spine was lower $80's. The most I saw a spineless copy sell for was $175 I think. The spined copies were consistently $120+.
After losing auction after auction I finally found a buy now listing that was $102 shipped, and I felt like I got a decent price as far as eBay goes.
Be wary of seller yyygfgh or something like that. I bought a copy from him for $94 shipped. He marked it shipped within 24 hours, but did not provide a tracking number, and gave me some line about Japanese post do not provide tracking or some BS, and told me to be very patient because it takes a long time to clear customs. After hearing this I knew I was in for it, because I've bought from Japanese sellers before without a problem, always get tracking, and always receive it within 2 weeks, most of the time much quicker.
Well after 3 weeks and no game I contacted him again, and again received the exact same response.... customs etc. So I opened up a case with eBay and he promptly refunded my money. I guess he never shipped it since he refunded so quickly and I never got it in the mail. I think he may list games that he does not actually have on hand, but ones he feels he can readily find in Japan, and I guess in this case he couldn't come up with one.
Oh yeah... You can't have my copy either.
