Yea, I'll go against the grain here also. I own four Kimber 1911's, and all have performed very well indeed. More accurate, and better fit than my series 70 & 80 Colts. Reliable in the extreme. I wouldn't spend the money, and keep buying them if they didn't work.
If the Colt name is important, then, as been said, they have really increased quality in recent years, and are probably a fine choice.
The $900 price is really dependant on the model. The basic, fixed sight models are usually a few bucks less, the next step up, the "custom Target", with adjustable sights, usually a little more. From there, the sky is the limit, with many models in the $1200 / $1400 range, or more.
My Custom Target is the most accurate 1911 I have owned or shot, and has never jammed or malfunctioned. Not once in thousands of rounds. The only problem I ever had was on my 10mm Eclipse - a bad magazine. An easy fix.
Customer service? Years ago, I bought a used .22 conversion kit. Was never completely reliable. last year, on a whim, I sent it back to kimber asking if they could take a look at it. A couple weeks later, no questions asked, a new one showed up at my door, no charge. I own three of their rifles as well. I guess I am a bit of a fan boy, simply because they both look good, and work.
