I have to stand by my recommendations of current production Colt or the "E" series Smith. I'll agree that the STI offerings are just as good (except the Spartan, which is good, but not quite that good). It's just that the Colt and Smith are also good value for the money. The best non-custom 1911 on the market is Dan Wesson, but I doubt you'd find one under $1,250, even used.
If you're willing to go used and build up a custom gun, the old Norinco imports are great deals. I'd also recommend Caspian for a build.
