American Tactical Imports? Hit and miss. I had one of their Commander models and had nothing but bad luck with it. The front post on the ejector broke; the extractor, which was far too soft, deformed and would not pick up the case rim; and the firing pin stop cracked. That was all before it got to 500 rounds of standard .45 230gr ball. Also, if you get the standard model (opposed to the enhanced), you will not find a standard sight set that will drop right in as the slide dovetail cut is not Colt spec (it is over by at least .020" on width). After replacing all the parts, I ended up trading it in on an SR1911 (which has been amazing).
CZ-75 P-07 can be found in that price range if you shop around a little. At first glance, I didn't think I would like it but it feels great in the hand and functions flawlessly.
