Have you owned a 1911 before? If not, I would start with an all-steel, 5-inch gun in .45-caliber. As others have said, there are a lot of nice guns in that price range. I would probably pick an S&W but you couldn't go wrong with a Colt if you think you might sell. Everyone seems to think Colts hold their value.
If you are a target shooter, adjustable sights are nice. Maybe something like this?
Product: Model SW1911
Pretty basic gun but nicely set-up.
