I have a Kimber Custom Target II and it has performed flawlessly, I paid $1050.00 for it. I also have a STI Trojan and it has performed flawlessly, is far tighter, and definitely is better built in my opinion, I paid 1200.00 for it. I'd pay the $150.00 extra for the STI every time now.
Just one point: the slide serrations on the STI are sharp, no burrs but sharp and easy to grasp. The serrations on the Kimber are there as if for looks, they are not sharp and provide far less grip. Many details like this separate the two guns.
