I use an old battered SM58, and it is a good solid workhorse, a mate of mines band bought a cheaper brand that were supposed to be much better, salesman told them the Shure was 30 year old technology and out of date. Another mate of mine 'in the biz' told me, 'maybe, but the reason they get used is they will take the punishment, some of these 'better' ones once dropped will die'.
Guess what, he was right, as their stumble bum lead singer dropped them they broke.
So, if you can get a genuine one...
