Looks nice, had never heard of this gun, is it rare, affordable, etc?

Thanks SPUSCG.
The following link provides a little history of the gun.

There are several variations of the Radom VIS.
Those manufactured prior to German occupation are more "refined" and, I believe more rare, thus more expensive.

What are those controls, like a safety and a decocker or something?

The controls on my VIS include an extended slide release, decocker, and a take-down catch.
The take-down catch was ommitted on later models in an effort to speed up production during later part of WWII.
