Craft Holsters is the U.S. arm of Falco Holsters from Slovakia. I just received one of their open top iwb holsters for my CZ83 and it's great. When I placed the order I did so on Falco's web site, but the confirmation e-mail came from Craft.
Very stable and concealable, and the reinforced mouth is stiff enough that it doesn't collapse when the gun is drawn, which makes for easy reholstering. However, I believe that each holster is "made to order", not shipped from stock, so the wait is pretty long. I was't too concerned about the wait, as I have a Don Hume belt-clip iwb from my Bersa .380 that fit my CZ83 fine, but it's not nearly as stable, comfortable, or secure as the Falco.
