You are absolutely right Epoxy7. There are some sellers in Canada that have an excellent price on the base (blued CZ-75) model, but go up one or two hundred dollars, or a third of the price, on the CZ-85 models, especially with the nicer finish.
While this is fair, it means that the price of your CZ gets jacked up into Glock territory, or even refurbished Sig territory. Also, to remove the trigger and magazine drop impediments on a CZ-75 could cost you money. So the price starts to escalate once you try to make it comparable with other modern Western handgun designs that have good triggers and drop-free mags. You have to mod your CZ-75 or buy a CZ-85 Combat. So is it really a good deal? If you absolutely have to have a particular CZ model, then yes, it is.
I ended up going with a nickle CZ-85 combat. I absolutely had to have nickel, as I hate maintaining bluing, so my choices were limited.
There are some really good prices from Wolverine and Guns and Things on the various CZ-75 models and some of the 85s, so I'd say go ahead and get a CZ from them if you are looking for blued. Once you get up past $800, it makes sense in my view to get a Glock or Sig.
What makes the CZs special is the finish options that are not available on Sigs or Glocks, so if that's a special point for you, then get the CZ. Otherwise, SIG is a great pistol if you want to spend a few hundred more. That is comparing apples and oranges, though, as CZ is a steel pistol designed for 1911-style grip lovers, and the SIGs are polymer wide-grip designs.
I'd choose based on grip and what you shoot accurately. P226 is an excellent pistol, but make sure it fits your hand first. I have a Norinco P228 copy and while it is one of the most easy-cleaning and reliable designs I have ever seen, I think the P226 might be a bit "chunky" for me. The CZ-75 feels like a "real" pistol.
