I like the Sennheiser 835 mics for vocals. For instruments and vocals I have a Shure Beta 57A. For instruments primarily I have a Sennheiser E609 and a Shure SM57.
MXL has the large diaphragm 990 and small diaphragm 991 packaged together as an inexpensive set and they can sound very good. I use the 990 for some room 'air' and close mic with the 57 or 609 when trying to record guitar. The pair of MXL's used together can really do a nice job recording an acoustic guitar.
