haha, nice find!
I have a Hyrulian shield from a dress up party about 9 months ago, I bought a generic plastic shield and painted it though. Seems it saved me $140
I also did much the same with a plastic sword, and even went so far as to purchase a blue ocarina and spend a couple days learning a few songs on it.
I got my Ocarina from a music shop at warringah mall, yer not the best quality but at least it plays the notes (since then a friend bought me a good clay ocarina)
