To me, they are the finest pistols to ever use CZ's design. They are jewel-like in their fitting, refinement, and attention to detail. ...and just flat-out beautiful to boot. Even the roll marking is done with amazing precision. I'm not really speaking about the production grade SDP guns, but the 2000 and 3000 series are special pistols, in my opinion. If I had to choose the top five highest quality post war semi-autos ever built, these Sphinx would make the list, namely the AT2000S. That's how highly I think of it. Any thoughts or pictures to add? Here's one of mine. AT2000S with a stainless frame and carbon steel slide with the palladium plating.
