This is an expensive one...very nice mic, been around for a long time. Neumann makes good stuff:

This was probably my favorite one to use at school. Very warm and crisp sounding. Tube mics > *

Haven't used this one, but probably very similar to the above one, quite a bit cheaper though:

I imagine these are a little on the expensive side for a gift though.
Any more specifics? Accoustic guitar? Need to mic amps or drums or anything?
