I bought my own copy off eBay a few years back. It was one of the first actual anime movies I ever watched (my friends rented it every now and then). Years later, when I got into anime from another angle (Starts with Dragon, ends with Z), I looked it up and discovered what had been done.
After I collected what I could of the original (US DVD, Japanese limited edition DVD box set, Japanese collected manga, US manga box set, US unflipped large-format set), I had to get the Warriors of the Wind VHS simply for nostalgia.
It sits between my Ohmu figurine and Nausicaa statue.
