I'm a Springfield fan, but the Auto Ordnance 1911A1 looks like a decent low cost repro, although I have no personal experience with one. As well, the Regent looks ok, but I've never actually met anyone who owned one/gave a review. Handled one (that's been sitting in a local shop for going on 2 years), doesn't impress me. The Remington isn't even an accurate repro of any USGI pistol, so its out as far as I'm concerned in this repro category. The Norinco...is a Norinco.
All that being said, any new GI-type pistol will probably shoot and perform as well as the mass produced war-time pistols that 1911 lovers covet so much.
Just wanted to add a few thoughts.
