I assume that you want a new gun. If so, then you can knock Wilson, as well as Ed Brown off the list as neither shop offers anything for under $2k.
I myself would go with either Les Baer or Springfield Custom. You could also go with the original Colt, but I prefer my 1911s to have more bells and whistles than Colt provides with their pistols. Kimber makes a good gun, but I don't like the Schwartz safety and to be honest I think the guns are overpriced for what you get (e.g., pistols chock full of MIM parts, plastic MSHs, etc.) S&Ws are good, but I don't like external extractors on 1911s.
That brings us back to LB and Springfield Custom. Baer makes a gorgeous, super-accurate 1911 with good old fashioned bluing, just the way I like. He uses all tool steel parts in his guns if that is important to you. Firing one of his guns is a supremely enjoyable experience.
Springfield Custom is the shop the builds the Pro, AKA as the FBI gun. The guy who heads the shop is Dave Williams, 2006 (I think) Pistolsmith of the Year. The Pro is over your budget, but you can get the Custom Carry which is the Pro minus some of the FBI's specs. Do a search for the Pro or Custom Carry and you'll see that those that have these guns love them.
I myself have only two 1911s. I don't collect guns, I like to shoot everything I own, so I decided early on to choose quality over quantity.

You should try to do some more research before you decide. Here's a website that I found very helpful when I chose my first 1911 -
