I like the STI Spartan and SA GI in that price range, Of course the Spartan may need to be on sale to get in your price range.
I own a PT1911 Taurus which i like alot and it shoots wonderfully, But i don't feel the quality is all that good even for a $550 gun.
What i mean is the gun has a great feel and look, But how many rounds and years it will last is not a lifetime imo. Unless i send it too Taurus continually.
Im not knocking the gun, I trust my life to it 3/4 of the year as my ccw.
But ive just seen to much unnecessary metal wear and softness.
Of course my exterior is well worn as they use a very thin blueing. If you do go Taurus buy the Stainless steel version and it may be an all new ball game.
I like the look of my worn blueing from carry, But if you look inside and i showed you some of the internal wear its beyond acceptable imo.
BTW i think im around 1300 rounds.
Mabey i should contact Taurus since im not carrying the gun in the summer and see if i can at least get the slide replaced. That ought to look dumb with my well worn reciever.
But i could just send it off for a DuraCoat treatment.
