The discussion touched on this but a very good alternative to full custom, and less costly, is Les Baer products. I have one. They are extremely well made, available with any variety of features and I have never seen a more accurate 1911. The barrel to slide and slide to frame fit is unbelievably tight. Comes with an excellent trigger, though you may later want to lighten it up. After 150,000?? or so rounds and you wear it out, send it to the factory and they'll rebuild it for you. They are also nice people to work with if you ever need parts or to deal with the factory. You will never be sorry and unhappy with one of these down the road. My best suggestion is to go to a range/gunstore that has rentals guns. Shoot a Kimber, Springfield [or something else] and a Baer Premier II ($1600. Loaded), one of the less expensive but fabulous models. This exercise will cost a few bucks but also be fun and a great experience. It may keep you from making a bad, costly decision. Then you will be able to make a wise decision and know the difference and what you are talking about. Let that comparison and experience tell you which one you should buy.
Oh yes, also the resale value.
