First, I'm shocked to learn about Stephen Camp, I'm glad I bought his manuals from him before he passed away. He lived just north of us here at DFW.
On topic: I owned the BHP before buying a CZ-75. As schmeky said: they are nothing alike internally. When I bought the CZ-75, I thought the same thing when I looked at the BHP. They do resemble each other.
The first time I disassembled the BHP, I was amazed at the simplicity of the design. It is pure genius. What I don't like is the later addition of the magazine disconnect, which screws up the feel of the trigger. However, even with the magazine disconnect, the trigger was better than the creepy trigger on my two CZ-75's (9mm and 22LR).
The CZ-75 has been copied as the Baby Eagle (Magnum Research) and the EAA Witness. EAA also imports the EAA Witness Elite versions that are made in Italy. The Elite versions are fantastic. I bought the Elite Match first, followed by the Limited, and finally got lucky and was able to get the Gold Team.
There is also a SAO CZ-75 that comes from their Custom Shop. I've shot it, but I don't think it is as good as the EAA Elites, but that is just a personal opinion and I can't give specific facts, I just didn't like it as well.
The EAA Witness Elite MSRP's are much higher than distributor cost, so you should be able to get one less than the MSRP.
