Tapermark:
I have another recomendation for you. Since you already have a LD and a SD condensor pair, maybe try a pair of the small electret omni-directional microphones. They range in price from $19 each (Naiant Studio) to thousands of dollars (Earthworks) with many inbetween (Church Audio, Sound Professionals, Core Sound etc...). I find these microphones make very life like recordings and are often overlooked for various reasons.
I do, however, agree with Teddy, that it's hard to beat a ribbon microphone for acoustic music.
