i have a camo one and a black one like that. they're fun to spice up with band patches and stuff. i made a patch with my boyfriend's band logo on it and put it on the black one and his other guitarist rocks that thing all over the damn place.
i got the black one at the Electric Chair for 10$ and the camo one at Dee-Lux for like 7$ i think. Hot Topic is infested with them, but their's are more expensive and usually have a band logo on them.
PM me if you're interested in a custom purchase still, i'll hook you up
ps. if you look on eBay, search for "cadet hats," they started off as a military issue thing. it's what they give you in basic so they call them "cadet hats"
