you could just get a black wooden sword. Though I did hear something about ichigo's sword when I went to Excalibur.
80s sounds about right though, when I got my shinigami costume I remember it being expensive because bleach had just come out in japan and so they could auction them off with lots of bidders.
a hint though would be to alter your search a few times, sometimes overseas sellers don't list stuff too well.
go like bleach , ichigo, bankai, shinigami just use various words that might not be obvious. Captian aizen pulls up a couple results too
That being said, if you order something from china expect it to take over a month to come. If you order it in august it might not be making it.
