Which SM58? Im a bit banboozled, i used to think they were all the same..

hi everyone, I need to buy another sm58 but Im a little bamboozled with all the variations of different types of shure sm58s. if anyone has a minute, could you help clear up which model is good enough for stage performances? eg, I saw one which was an sm58 but was described to be more ideal for studio recording as opposed to live events.

Its for a mobile disco, im between getting a mains powered radio mic sm58 and a standard sm58 connected by a joyo xlr transmitter so i can have a cable option available too.
