I once paid $10 for a Moulin Rouge swizzle stick.
We were in Las Vegas at the time, so that makes the stick from Vegas. However, I don't know for sure that the stick was from the Moulin Rouge in Vegas.

Most of ours were under $1.00

The glass ones were more

I paid a lot for our boxed set of swizzles (click the link below), but I've never seen another set...and I love it, so it's o.k.
