When I bought my SIG Pro, I got the 'Blue Line Special' which is marked 'Blue Line' on the top of the slide and came with three mags but only the one grip panel. $450 was the asking price. At the same time, he had the non-Blue Line version which had two mags and two grip panels for about $530. I don't think I've ever seen one for more than $530.
Around here, CZs range from $380 (standard 75s, SAs and BDs) to $440 (P01, RAMI). Sp they aren't quite an apples and oranges comparison... I figure discounting the Blue Line, you can either get a the SIG Pro with two 10 round mags or a CZ75B with two 10 round mags, two 15+ round mags and a High Noon holster. Different areas will differ of course.
Between the guns, I had a SIG Pro and sold it within a couple months, preferring the G23 for the similar role. I love CZs and have probably owned six of them and have a PCR on the way. For my desires, there is just no comparison. I would out the 228 or 229 on par with the PCR/P01 and then the prices are dramatically different. I just prefer CZs I guess... Not blind to the plusses of SIG, just the CZs feel much for comfortable to me and are basically just as realiable at a lower price point.
Bersas aren't in the same league... In my opinion.
