You really need to check these websites out... they have incredible looking, and from what i can tell from the sound samples, sounding mics for really dirt cheap. Avant electronics, Cascade, and Joe Meek. I have a friend who has a few cascades... for the price i don't think they can be beat. oh and come come with switchable capsules so you can get different polar patterns.
Not much of a stretch to go for a pair of Avenson STO-2. Of course the stretch ($50) gets you a pair and not one mic. That mic is detailed, has fast response and does room AND close mic'ing extremely well. They simply sound like where you put them, but not boring!
