Audix OM2

I went into a music store the other day thinking I'd buy a Shure Beta 58A mic for live vocals. They didn't have any and I got talked into picking up an Audix OM2. I tried it out with the band last night for the first time and I was seriously impressed, what a huge difference over my SM48 and 57. I can't find many reviews of the OM2 online but so far I'm really happy with it.
