I have 2 SM58s and 2 SM57s, and I like the sound of the 58 for vocals better than my MXL 990 condenser mic. It just seems "richer" somehow. I will use the condenser and the 57 for "gang vocals" when I want to sing the same parts in unison as if there was a group singing together, just to give the supporting vocals a slightly different timbre. The 57 seems to translate more of the bottom end and sounds deeper, so I get that effect when needed. Otherwise I use the 57s on drums. Watch the resale sites and browse the used gear on Guitar Center's web page. I found the MXL for 39 bucks on Guitar Center.
