Internet scripture? Cool.
I'm a bit more ambivalent about the lock thing.
I don't care for the looks - that's subjective.
It has a non-zero chance of glitching up - that makes it infinitely more likely for a lock-equipped revolver to have a lock-related problem than an non-lock equipped revolver to do so (duh) - division by zero and all that.
I believe it's massively over-reported based on the following experiment:
Enter the words "michael", "bane" and "lock" into Google or your favorite search engine. Looks like there's several dozen Michael Banes each of which had several lock incidents. Since there's only one Michael Bane reporting one incident I am forced to conclude that everyone, his horse and his half-brother has made note of the incident - in writing, repeatedly, on the intertubz. I believe we already have one in this thread. It's probably an exaggeration to state that Michael Bane's lock whoopsis has been reported 10,000 times but I'd bet it's at least a 1,000.
I tend to be guided by those that actually sell or have sold the things. My favorite along those lines is this from May of '08:

Recently a thread on ARFcom, complete with pictures, concerning yet another spontaneously-locked revolver has triggered yet another flareup of "See? I told you so!" on the web, including posts from people on Evil Black Rifle gun boards who are no more likely to carry a S&W revolver than they are to sprout wings and fly.

"What?" you say, "You own Smiths with locks?" Yes, I do, although I cordially dislike the little bugger on mostly aesthetic grounds. The two Smiths I own with locks are models that I wanted that had no pre-lock equivalents, so it was deal with the lock or deal without the gun.

I (very) recently have caved in and have one such. Like the lady said, sometimes it's deal with the lock or deal without the gun. My preference is without the lock.
I'm of the opinion that if one were to put a pencil to it, actual lock failures number far less than the number of other failures with anyone's revolvers. The lock is probably a bigger issue for those that actually believe revolvers never mess up anyway - that's more internet scripture - "six for sure", "always reliable". I've never bought into that gospel so I tend to view lock related failures as just another mote in a universe of guns screwing up anyway.
