In May of 2011, I purchased a Springfield Range Officer for $750 - great deal. Nice gun, and it should still be within your budget, today. This December, I added a Dawson fiber optic front sight, a Smith & Alexander mag well, Rosewood Hogue grips, and an Ed Brown extended magazine release (don't have big hands). It is a good entry level gun, and the additions were made to address specific issues I had.
I don't know what your wife likes, but I cannot say enough good about the 1911 platform. A nice 1911 really enables a shooter to perform to the best of his or her ability without any excuses.
