CZs are great pistols. They shoot well, and I find them accurate.
The basic models are reasonable in price, for a well made all steel pistol, at $500-600. The triggers on them are not the greatest out of the box usually, but they smooth out pretty nicely after a few hundred rounds. Swapping the hammer spring for one a little lighter is a cheap easy way to improve the trigger pull.
There are companies, like Cajun Gun Works, that specialize in gunsmith tuning and custom parts to improve the triggers as well. I hear nothing but good things, with some stupidly light trigger pulls available if you want a target pistol.
Move into the competition ready stuff, and you spend about double, but you get a very smooth pistol for that money, with a nice trigger. Their SAO versions have some very nice out of the box triggers. Fit and finish on them is better as well, which likely results in better accuracy over the already accurate standard models. Plus they get upgraded grips, and I believe a couple more mags in the box than the standard models.
The Shadow II is very nice, its not the highest end of their models, but I think it hits a good ratio of performance and cost.
The EAA Witness is a CZ clone, and they are a little cheaper than a CZ, with the competition versions being a few hundred cheaper.
They are nice, but they are not 100% parts compatible, so aftermarket may not be the best with them.
There are other all steel 9mm pistols out there, many are mentioned in this thread.
