While a ribbon microphone may not be the best choice for every application, it's certainly nice to have around; I found that the RSM-4 added a much-needed flavor to my current microphone collection.

Guide Review - Nady RSM-4 Ribbon Microphone
Ribbon microphones are relatively simple pieces of electronics. The ribbon itself - usually made from a type of aluminum - is stretched within a magnetic housing. They're very similar to dynamic microphones in that they offer high SPL levels and don't require phantom power, except they offer many sound traits usually reserved for condenser mics, including an extended high-frequency reproduction and accuracy of texture.
The Nady RSM-4 is a no-frills microphone; packaged simply and including only a mic clip accessory and storage box, it sounds fantastic right out of the box.
Acoustic guitar shimmers with very accurate high-end reproduction (the low end is accurate and boomy, sometimes too much so, but that may have more to do with positioning than the mic itself). Guitar amp sounds heavy and crunchy, and a little EQing in the low-mids puts the mic in competition with the Royer 121 I tend to favor (although the Royer still exhibits better low-end control and high-mid accuracy). Vocals sound good, but instruments are where the RSM-4 shines. On drum kit, the RSM-4 sounds great on high-hat (especially brittle, cheap-sounding hats) and on ride.
The best part is the price - recently, the RSM-4 has been priced as low as $69! This cheap, it's well worth getting two to use as a stereo pair; they'll meet and exceed your expectations at this price.
I'd call it the best camera for that price. I'd go for it.
FYI, Downsides are:
* Limited lens compatibility (no autofocus motor, so many Nikon lenses won't work)
* Autofocus is slow enough to be completely useless in live view mode (try it in a store)
* Video mode isn't up to par with Canon and friends. You get limited resolution, awkward frame rate, horrible audio (11kHz with low quality built-in microphone, and no microphone input, and the kit lens will give you lots of image stabilizer noise).
Stepping up, Canon 550D is an amazing camera (albeit without the pivot LCD)
