Time to move up to "Big Boy Toys". Based on hours of research, I THINK I have my choices for a good quality/value vocal mic narrowed down to 2. Rode NTK or Studio Projects C3 (has addtional features over the C1) I have found pricing within $50 between the 2. I'm trying to stay under $500. Any thoughts?...kpl p.s., I see interesting discussion on Mic-Pre's. Are these really necessary? Anything in my lower budget price range? Current setup: Mackie 24/4, into Layla 24/96, into Cool Edit Pro/Sonar.
