I've got a pair of Rode NT3's. I initially used them for drum overheads, but I find my self reaching for them more and more. Really great sound on guitar cabs and acoustics.
I was in a studio the other day and they miked up my glockenspeil with a pair of NT2's. I was stunned at how good they made a toy instrument sound. fantastic sound.
Im probably going to get an NTK later, when I can afford one. Being an australian, they are nice and cheap over here compared to the imports, and I wont have to worry about the power supply being 110 Volts.
