Seattle, WA X-Wing Helmet needed

So, you guys know the Fremont Solstice Parade? Well, this will be my fourth year with the pre-parade cyclists, and a bunch of us are planning a Star Wars paint theme...and I would dearly love to be an X-Wing pilot on my rollerblades.

PROBLEM: I can't find an X-wing pilot helmet that fits my budget; I'm on the broke side of the Force.

Does anybody know where I could get an el cheapo X-wing helmet, maybe Halloween costume-grade or something? Or does anybody have one they'd be willing to lend for the parade? Thanks in advance for any advice or offers!
