For a period of time, from 2004 to around 2014, M-Audio made a series of affordable, quality microphones. One of these was their Tube microphone, Sputnik. I picked the first one up around 2009 and love the sound so much that I eventually bought a second one. Both come in a cool, sturdy, metal case. The power supply has a retro-Soviet vibe, the 7-pin cable is super long, and the polar patterns, pad, and low-cut filter switches are directly on the mic. Both have had a low amount of hours of use. Asking $450 for each, or $800 if you take both.
