10mm or .40 S&W

I'm thinking heavily of getting a 10mm auto-pistol. I'm thinking real heavily of getting an EAA Witness Steel frame Wonder Finish 10mm Auto-Pistol. It looks like this.

I know, it looks a lot like the CZ-75B. Well, gee, so did the Bren Ten. The first 10mm auto-pistol was based heavily on the CZ-75 series. I'm told this is a good pistol, not real expensive, and it works!
