For a thousand dollars I would take a Springfield Armory "TRP" model over buying a standard Kimber and getting it reworked. Just my opinion, I have heard some really good things about the TRP guns. Here is the official Springfield web page about them:

Here is a stainless TRP for $1079 new in box on gunsamerica.com.

HKocher posted awhile back that he sold his HK USP Tactical .45 to buy a TRP "Operator" model, and told me to do the same as he says the Springfield will easily out-shoot my $900 "big Tac." I couldn't believe it, he is a big HK nut just like I am, so to turn his back on his Tactical and tell me that the Springfield kicks its ass really means something. Just to give you some idea of the reputation these pistols are garnering.
