Shure KSM series mics seem to be rather popular on live sets lately. I've seen quite a few Austin City Limits and another performance show on PBS using Shure KSM series mics on stage. Most recently, I saw Allison Kraus and Union Station perform live with a few. Sounded great! Also saw the Dixie Chicks do the same on a live concert on NBC a while back. The KSM series seem to be quite the bang for the buck ... thousand dollar sound without the worry of carrying multiple $2800 U87s on stage.
