I was in the same boat as you about 5 months ago, Rugerfan. I bit the proverbial bullet and bought a no frills Kimber Custom II and have not regretted it! It was indeed expensive, especially because I got it from a local shop instead of online but I have had NO problems out of it. I broke it in properly (the guys at the range were ridiculing me, but hey, I do things by the book when it comes to a $699 piece of hardware) by taking down the slide, wiping it, re-oiling it, and cleaning the barrel every 50 rounds for 500 rounds. I have put maybe 2,000 through it and I was impressed with the very first shot. I just can't say enough about my Kimber! Also it has the firing pin block and all that "malfunctioning" stuff. I can't really see the problem with it but it is all very easily removed if it ever becomes one... its just a spring fed bar under the slide with a small metal rod that pushes it up with the grip safety. Detail stripping a 1911 is so easy I learned how to do it in 10 minutes from watching a video on YouTube. It will really get you into 1911's as well as modifying them!
I am also one of those who were gipped by Taurus, both with a horrible factory out of the box pistol AND the nasty customer service. I will never stand by or recommend them again.
As for the RIA, my cousin recently got an officer's RIA and despite not shooting it, I did break it down and play with it and it seems to be a very solid 1911!
