I have a Kadet Conversion Kit that can be mounted on my CZ-75B, 85 Combat, or Custom 75B SA. It is amazingly accurate. It was as accurate as my Ruger Target Competition (Slabside) with the long barrel, which I later traded away. I love it. I sometime use it when I practice for IDPA.
But the Marvel conversion unit for the 1911 is a true match-grade target .22 and is the most accurate .22 unit you're like to encounter. (Bullseye shooters use them to practice with their .45s and for competition.)
Both conversion kits require a top-notch lower.
The other option is buying the CZ Kadet, a dedicated .22 -- the standard CZ lower with a .22 upper. I would not buy a CZ Kadet (the .22 pistol); I would, instead, add the conversion kit to an existing CZ in 9mm or .40.
If you already have a CZ-75B or similar CZ, and don't have a 1911 that has a great trigger, then the Kadet Kit and a first rate trigger job would cost about the same as the Marvel.
If you already have a top-notch 1911, then the decision is a little easier -- get the Marvel and mount it on your 1911 frame. If your 1911 is only so-so, the decision isn't as clear.

Don't be so sure of the inadequacy of CZ triggers... While most of them (in SA mode) won't break like a top-notch 1911 straight out of the box, neither will most 1911s.
On the other hand, I've got two CZs that I'd stack up against ANY custom 1911, Wilson, Baer, Ed Brown, etc. And they'll also shoot smoothly in DA mode, too.
