I think there's actually hardly a difference in the hits you get on the Japanese version of Google versus the English (.com) one, unless you restrict your search to only include English or Japanese language pages of course. I just tried and was able to find the same info on the English Google page as well. Did you do a search using the catalog number, LuxKiller65? I wish Google would make it easier to switch between the different language versions...
SS, the auction I linked to looks like a good deal. There's a sealed copy up too for the same price (has some sunburn on the obi's back though):
