Jim you sound like you know what you're talking about.
I've been using a studio projects B1 and recently bought a B3 too that I haven't had a chance to check out yet. The B1 sounds bright to my ears though I've been told to use proximity to achieve deeper sounds.
Can you suggest a few $100 - $200 mics that are warmer?
I've been thinking about one from Kel Audio HM-1 for this purpose based on what they say.

I've also just picked up an inexpensive Nady ribbon mic RSM-4 (paid $70) with the intention of capturing more mids and lows.
