01991 great gun for around $850-$900 I own three in 2 calibers.
Loaded is a great gun. Mine is great.
RO is another great choice
Mil-spec. Excellent choice.
SR 1911 Another really nice 1911. Love mine.
DE1911G. Mine has the best factory trigger I have ever shot. Real nice guns for less than $700
Remington has several models for less than $900.
Spartan. Great guns. Mine in 9mm is a blast to shoot.
RIA, ATI, and Metro Arms make some great guns for the money. All 5 of mine have been perfect so far. The good thing about them is you can get 2 for $900.
There are others but these all have great warranties and would be the ones I would look at.
