Shure KSM137/SL
I brought two of these mics from Front End Audio, as always the processing and delivery was prompt and they arrived here to NZ safely packaged.
As for the mics, I absolutely love them, I have recorded two classical guitar pieces with them so far to which I used very minor console EQ to subdue the transient detail, straight off the desk was fine and wouldn't have required any such EQ if going in the mix with drums and guitar etc (in that situation I believe the transient detail would have been a total benefit).
With these mics on classical guitar there was no requirement for corrective Hi-Q cuts at all - great!
I'm yet to use these on drumkit, however I expect the transient detail in that situation to give a brilliant picture of the drums.
