WTB: Mics (Audix, Audio Technica, Sennheiser, etc) & Mic Pre's

[Silverwulf]

I'm looking to pick up some additional mics, a good mix of both good and low end mics for some variety. Models I'm currently interested in are:

Shure SM7
Audio Technica ATM-25
Audix i5
Audix D2
Audix D4
AKG D112
Rode NTK
Behringer B1
Studio Projects C1
Sennheiser e604
Sennheiser MD421

I'm also looking for a good quality mic pre in the lower-mid priced range of about $400 - $600. I'm open to suggestion to units in this range. PM me with anything you my have. Thanks!
