The Red Type B with the interchangeable capsules is probably the most versatile mic in the sub $1000 range. You can find more information about it a http://www.vintagemicrophone.com
I use one with the R6 (C12 type) capsule for both vocals and guitar. It's absolutely stunning. The R7 capsule is a (U47 type) capsule that is amazing as well.
If you're in the market for a good mic, they are definitely worth looking into.
