I just made an account to jump in on this question, and maybe I'll follow up once I own a CZ pistol.
I just purchased a Skorpion from CDNN, I was told they have 7 or 8 left, all nickel. In older CDNN ads, it shows the same price for blued or nickel, but the nickel ones were apparently far less produced. Anyway, after the 14th, one of these babies will run you $712.00 with shipping. That's before FFL fees, and in my state, 9.5% sales tax. Hard to swallow that price when I look at old ads at $399.99! I've wanted one forever, and I already paid for waiting, I imagine they'll only become harder to find. I hope I love it, because said and done, we're talking $808.00. Ouch.
Search engines will bring up a few sites advertising them, including Bud's, but through much research, they're all old and outdated ads.
