"Another mic I just sold a few years ago, a Shure SM58 was also a lovely performing mic that was every bit as rugged and reliable as the RE-15."

I truly believe the old SM58s were made better. The one I have sounds fine, but the rumble it picks up is the worst of any of the ones I own, including the lowly Samson R11. And they are 3 for $60.
