There's no need to go THAT expensive to get good audio. You can get excellent sound from reputable manufacturers for a lot less than $500. I have the AKG D5 and it's an excellent dynamic (live sound) microphone with a supercardioid pickup patter and excellent feedback resistance. I paid $70 for mine.
RODE from Aus has several microphones that sound excellent, are well-made (not in China, but in AUS) and also are affordable.
Why go bottom of the barrel no-name microphone from a mystery company when good quality from reputable brands is not much more?
