This is the absolute best mic on the market for live vocals unless you have an unlimited budget. I also own a PG-58 and some cheap Beringer mics that work, but the SM-58 has a slightly better tone and does not transmit noise when holding it or adjusting the mic stand. Don't be tempted by mics with on-off switches- you don't need a switch and that is always the part that will fail first. Kill the mic at the soundboard like a pro! I expect to be using my SM-58 for years to come!
