I use a rode NT4 that you can find for around $350. It's rigget and a fantastic value, but the mikes ate permenantly set at 90 degrees. I've used the high end Sony ECM-MS957. Not the most transparent sound in the world but you'll get decent recordings. You can find it for around $150 to $300 The Audio Technica AT822 is a very rugget mic that makes nice recordings as well. It goes for around $200. But I would try not to use the automatic mic sensitivity settings for your MD because there are clipping issues which may cause your recordings to come out too low or sound "jerky" between dynamic highs and lows. I always set it to manual and watch the signal, especially if your mics are underpowered, there can be a lot of distortion. But if you set it to "loud" it increases the sound pressure level of the mics by supplying them with more power (not good for battery recording) but it can help you to have cleaner sounding recordings in the end. But when recording loud music, make sure your mic has a high sound pressure level (SPL) rating to agoid distortion. I hope this helps, cuz I've made a lot of mistakes in learning this stuff!!!
