The 686+ was my first revolver purchase, earlier this year (now on my what...sixth?), and it is a great choice. I got the 4" and find it remarkably accurate and pleasurable to shoot. It's just a marvel, you'll see.
Only thing I've done is shoot it, clean it, and shopped around for grips (the hogue monogrip that came on it was a little narrow for me; I ended up with a Pachmyer rubber grip that covers the backstrap and makes full power .357s a little easier to hang on to).
