spending money on a high level of trigger refinement is probably money wasted rather than money well spent.
The results on the target are not the only way to quantify whether or not a trigger job is worth the effort/cost. There is also the simple feel of it, the tactile satisfaction of pulling a nice trigger is enough for me most of the time.
But no, I wouldn't spend much if any, on a CZ trigger because it increases the price into that of a STI, PPQ or one of the many others that are good right out of the box.
Some folks do think the CZ's are worthy of the extra $... more power to them, its not a bad call either way.
When/if CZ ever puts their Omega triggers in all of their pistols I might end up with more than one
