you are asking for it:
than buy mine, a Panasonic VW-VWS2 incl. selfmade shockmount for 75 Euro + shipping:
excerpt of it's specs:
power source: 1,5 V battery
directional characteristics: unidirectional ( stereo )
nondirectional ( mono )
frequency response: 100Hz to 20.000 Hz
sensitivity: -47 db ( o db = 1V/pa,1 kHz )
output impedance: 600 Ohm
S/N ratio: 67 db or more
cord: 3,5mm stereo mini plug cord length 300 mm
switches: off/mono/stereo
wind cut: on/off
it's an original japanese mic, I had bought it 2 years ago in Osaka, the selfmade shockmount works great, uses the mic's shoe to mount, is very stable, can be used to carry the cam 'overhaed',and of course is in good working condition, hardly any signs of use to be found.
