What do you plan to use it for? Rail or no rail? Willing to buy used, or is new the only option?
In that price range the first pistols I think of are a Springfield TRP, most any Dan Wesson, and a used Les Baer. I've never been a big Colt fan, but the Wiley Clapp model is a good one. On Arfcom right now there is a nearly new Dan Wesson Specialist in Duty Treatment finish for $1,275. That's a fantastic deal even in this buyer's market.

https://www.1911addicts.com/forums/firearm-classifieds.20/Used Les Baers will come up regularly under $2k as well as some Ed Browns. If you wanted to stretch your budget a Guncrafter No Name is about as good as it gets below $3k and you can find them used for $2,200-2,400 if you are patient. It is a very soft buyer's market right now, so I'd strongly suggest buying something lightly used and letting your $$$ go farther.
If you want to buy new then Dan Wesson would be at the top of my list followed by Springfield, then Colt (because it will hold its value well), then Kimber (not thought of as highly in the >$1k market).
