I like CZ75 series a ton, plan on getting a BD next. I love the Beretta 92fs also.

The takedown on the CZ does kind of suck, but its not totally horrible. Its better than a 1911 or my Hi Power.

As for price, they are imported in lots, so when they come in the prices drop and steadily rise as supplies dry up.

Optics on pistols aren't really that big of a deal IMO. I've shot them multiple times and never found a tremendous difference between a red dot and open sights, unlike with rifles.

If you like a dot on your pistol, by all means use one. Its not a complete game changer though and you still need to learn how to shoot.
