I am a Shure fan, I have several SM 58's and Beta 87, but when talking about good vocal mic below 3K, I would recommend the Samson Q7, a supercardioid dynamic mic. Try it out. I used PG 58 and I'm using now Samson Q7's, and far off better sounding ang Q7. It's only below Php 1,700.
And if you look for more quality, papasok din naman siguro sa 3K category ang pre-owned na SM58. Pag may nakita kang SM58 on this price range('yung original ha, not imitation) na second hand, don't hesitate, kahit may edad na ang SM58, basta walang issues, it would last years pa.
