I'm a huge fan of the Schoeps CMC6/MK4. I use it for strumming, for finger picking and for a few different types of guitars. It's almost always my 1st choice, even among some other money's-no-issue acoustic favorites. I bought a pair for around $2500, so a single must be in your price range.

Also, maybe a vintage KM84, if you can get a hold of one.
