Hit the next gun show that comes up, see what's on the tables.
Go EARLY and look FAST. Every dealer wants to make an early sale: good luck for the rest of the show. Prices can drop amazingly for an early sale.
Alternately, wander around and check out the show, do your buying late. A small-value item like that can be discounted safely at the end of a show just to avoid the nuisance of packing it up to take home.
There's sure enough of them around, anyway.
