I think that the CZ-75 is as good as any $600 gun, maybe even those that cost more. It is just because of the differences in cost of labor that CZ's are so low cost. So yes, it is a deal.
The other thing is that while CZ owners uniformly think that it is great, they do not seem to drink the same water as some Glock owners. That is, while they love their guns they do not seem to believe that it is the be all and end all of handguns. Strength in diversity.
