I just purchased a CZ75B with the Omega trigger last week. For the money, I'm pretty impressed.
I got the Omega system mostly because that's the only one that comes with the upswept beavertail instead of the standard downward pointing frame spur, at least until you get to the pricier competition and/or limited edition models. I've tried the standard 75B and the grip spur began to wear a sore spot on my hand after a few shots. I use a high hold and tend to grip pistols very firmly, and really would not find the standard 75B workable. The Omega version grip is quite comfortable, on the other hand.
Also, there is talk that the conversion parts to swap between the standard SA safety and a decocker will be available soon. (Cool for IDPA use.)
The pistol came with two mags and was packaged in light oil, inside a plastic bag, inside a plastic box, inside a cardboard sleeve. I paid $480 + tax, I think. (Cabelas had them in stock.)
The only thing I'm not impressed with is the trigger. The SA pull is very light, which is fine, but has a lot of creep. The DA pull is impossible to describe in terms that are acceptable on this forum. "Heavy" and "stagey" begin to hint at it... and probably would be workable descriptions with a few expletives thrown in ahead of them.
I've gone through the lockwork and polished a lot of things up, and honed the engagement faces of the hammer and sear, but the trigger still has ~3/16" of creepy travel before the break. So far, there are no suggestions as to what can be done for the DA pull. A lighter mainspring is suggested by some, but that comes with reliability issues, as well as also making the SA pull lighter as well, which is counterproductive.
So much for the bad.
The good was range performance last practice night. Very fast. Very flat-shooting. Accuracy seems to be very good.
If I can get the trigger sorted out, I'll be quite happy with mine.
