Colt Series 70 repro, Colt Competition, Colt Combat Elite, and Springfield Loaded are all very nice guns and will serve your needs well and you can buy them new for well under $1000. I have friends with Rugers and they swear by them but if I were only going to have one 1911 it would be a Colt unless I was going to spend the money to buy in the Baer and Brown range.
If you're willing to buy used or shop hard for deals to keep around your price point the Colt Wiley Clapp Gov't Model is a lot of gun for the money. The DW Heritage is a nice gun, and used TRPs can be had for close to that and they are great guns as well.
Don't overlook the used market as well as internet sales, whether through sites like gunbroker or through forum classifieds like on 1911addicts, even some store/commercial sites can have good buys. In the last year I've purchased a lightly used 3 year old Baer Custom Carry for $1250, a practically new 20 year old Springfield Trophy Match $1050, a very nice old Brown-Baer Special Forces for $1150, and a NIB Colt LW Gov't for $750. A few months after I got it I threw $100 bill in with the LW Gov't and traded in for an as new Evolution Armory tuned 9mm Colt LW Commander with only 200rds through it.
Keep your eyes open, cash ready, and shop around and there's no telling what you'll find.
