Heh, well here we have them all again: RE-20, MD-421, MD-441, SM57,
PR-30,
PR-40,
M-88, all VERY GOOD Dynamic mic´s and also the Condenser CAD M-179.
I´m surprised the SM-7b has´nt been recomended yet....
I have them all, exept the CAD M-179.
My favorite would be the MD-441.
You asked about three of them, and my favorite of them would be the MD-421.
Don´t forget that when you will be talked into buying a SM7b, and you will...
you need a preamp that deliver a lot of clean gain.
Good luck!!
