Wow, I bought a new Bersa with the rubber molded Hogue style grips for $270 at Academy back in December. I don't know if you are able to shop on a military base but my Father in Law got a new Bersa for $265 out the door at the Air Base here...tax free shopping is nice.
As far as gun shows go. Every one I've been to lately is a total waste of time. Have you looked in gunbroker.com? Found several on there for less than $300 brand new.

"You cannot exaggerate about the Marines. They are convinced to the point of arrogance, that they are the most ferocious fighters on earth - and the amusing thing about it is that they are."
