The CZ grip seems to be very polarizing; it's either the most ergonomic grip you've ever set your hands on, or it's ridiculously bulky. The easy solution to this is custom grips. Of course, it's hard to get excited enough about a gun that doesn't fit your hand in the first place.
If you can find a SIG for that price, jump on it, period. Less bang for buck than the CZ, perhaps, but there's very little buyer's remorse with SIGs.
