Great gun. I had one when they first came out. Back then, however, I was not all that impressed with .40 S&W, and eventually traded it away. (I think I paid $275 for mine -- I'd love to find one fyr less than $500, now.) My 40B shot better in my hands than any .40 I ever owned until recently. (I've now got a couple of FNS-40s that I like about as much.)
I'd still like to find a CZ-40B, but whenever I find them, they've just been sold, or I don't have the money.
Keep in mind, too, that you can use regular .40 CZ magazine -- they won't look quite right because of a thinner baseplate, but they function well. (You may have trouble finding the CZ-40B baseplates -- but you don't have to have them. )
You did well.
