This one might be best in the Acoustic Music Forum - if you get the chance, feel free to drag it on over.
There are tons of choices for microphones that will give you the detail of the Earthworks without actually being the earthworks. My new personal favorites are Gefell M296. They will pick up a bit of room though, but I find it to be less problematic than both the Schoeps omnis or the Earthworks stuff. (Much more like the M50).
If you wanna go cardioid, the two other Gefells you mentioned are top-flight and you can't go wrong with them.
Otherwise, I do like the Audix SCX-1 and the SCX-25a's as being great cardioids at a great price.
Of course, there's always fig-8 mics too; Royers, AEAs, etc.
