I cannot answer on the frames, but the only particular issue I have run across in these reliable and accurate semi-automatics is worn components in the ambidextrous magazine catch causing the release to not work well from one side or the other, and that is not really a difficult fix if needed.
Otherwise, it is hard to go wrong with a CZ82/83 pistol. The only question I can think of is: "Do you want one in .380 ACP or in 9x18mm Makarov?". If you find one at a reasonable price, I doubt that you will be disappointed.
I am still looking for one of the few firearms on my active 'Wish List' - an affordable CZ83 chambered in .32 ACP.
