Earl,
Don't buy a mic by specs. LISTEN to everyone you are auditioning TYHROUGH the psr2000, if that's the way you will use it. The condenser mics will need phantom power too, so be aware of that little addition to your rig. You'll need some external power sourse to power the mic first if you go the condenser route.
I have had great success with the EV N/Dym series. The 757 and 767 are terrific stage mics and won't break the bank either.
They are hotter than most non-condenser mics, and rugged as all get out.
