The range in quality is massive.

Cheap mics are made to record sound just like cheap PC's can edit video, however quality is another matter. More expensive mics bring a new quality of sound (if used correctly).

For good quality recording you need to purchase a high quality mic. Its not all about brand name but purchasing the right type of mic is essential for value. Shop around for price but from experience I would always say, ask the people who know, find out what mics other production companies and freelancers use. There are so many people offering an opinion that I would stick to higher end users who could well advide you on a mic to fit your budget.

Dont forget, its not just a toy, its not like pointing and pressing record - technique is everything and getting the most out of your kit will reap benefits in the $$$ department.

Its not what you got but how you use it! (thats is so true!!!!! just ask my girlfriend!)
