I bought a Colt M1991A1 last November and have been extremely happy with it. It's got a better fit and finish than just about any Kimber or Springfield I've handled, and it was less expensive, too: $529. They're only getting better - the newest ones off the line have polished flats, a classy new rollmark, stainless barrels, etc. Mine has the original 1991 rollmarks and matte finish, but it's plenty for me. The only cosmetic issues are the long plastic trigger and flat plastic mainspring housing, but it shoots just fine with them. I'm only replacing them with G.I. parts because that's what I prefer.
As for that other crap (extended ambidextrous safety, beavertail, skeletonized hammer, "holy" trigger, slanted front slide serrations, ski-ramp sights) I think it's for pussies. The 1991 comes as a clean slate that shoots perfectly as-is, or you can customize it to your heart's content.
By far the best .45 out there for your money.
