The Custom II, TLE RL II, and TLE II are probally the best 1911's in that price range. S&W, Sig, Springy, RRA, RIA have all the same troubles Kimber deos.
The MIM isn't really a big deal. Lost of 1911's are filled with that. I'd recommend you look at K's basic models like the TLE and Custom II. Avoid the nightsighted models, your paying extra for obsolete sights on those.
If the MIM stuff really bother you:
-learn how to do trigger jobs, get the EB sear bar, and a hard Arkansas stone.
-get a W sear, disconnector, and hammer (W's premium linup requires very little fitting, except sear)
-EB MSH
-remove the FP safety parts, theyre MIM as well.
The only MIM parts I've seen fail are the FP safety, sear, and disco. The sear and disco took alot of shooting to kill.
Kimbers real problems are the old fashioned 3 dot nightsights, too fat front sight, horrid magazines, and the need for some ramp polishing. Nothing you can't fix yourself. Allmost all under $1000 1911 have the same issues.
