Springfield Armory (SA) makes EXCELLENT 1911s. Colt makes great 1911s as well.
Most off-the-rack 1911s made by either Colt or SA cost anywhere from $800-1,200.
Here is one of mine (a Springfield Armory TRP). This is a semi-custom gun.
Also, if you want a custom 1911, you could take a look at an Ed Brown, Wilson Combat, Les Baer, or Nighthawk Custom, to name a few.
Here is my Ed Brown Kobra.
