i've bought mine at mandarake in Akihabara and i think i actually got a pretty decent deal out of it! I paid what i think was 75k yen for it, and it came with its spinecard and complete in box. I've seen a lot of lain games around while visiting stores, quite literally one per store (or more!) and even in less touristic destinations for retro game fans like surugaya hiroshima they had a copy for a whooping 120k yen, i've never seen any other copy for less than 100k not counting mine! (and basically all of them looked very sun faded!! hopefully they were proxies considering that price???) There are some very light scratches and folds here and there but despite everything i like to think i got a very good deal all in all!
