bought one of these mics six or seven years ago and have loved it ever since. teied a bunch of different preamps (psp2, aerco, oade mod p2, and find i like the v2 the best (with an ad2k+ as the adc). i don't use it outdoors that often, and certainly not in rainy weather.
I would buy govt mule's mic (well known member here). I bought mine in Europe, and it was then checked out, cleaned up and given a clean bill of health from a mic tech in Germany who specializes in these kind of mics. it is heavy, so you need good rigging to hold it in place. I use the screw in the mic mount all the time. I did have to replace the screws that control the swivel of the mic mount, but that was no big deal. my foam windscreen is slowly falling apart, but hopefully I can replace that somehow; I was given a wonderful dead rat for outdoor use (that fits over the original foam windscreen) which is very effective
. I, too, have had cables made for it, but I don't remember the price (cables were made by the same mic tech in Germany); also bought a road case for the mic from the same guy (he makes them custom)-the thing would probably survive a plane crash...
go for it-you get a lot of mic for the price, and govt mule is well-known here, so no worries on that front. good luck. would be fun to have another c422 user 'round here.
