I purchased Dragon NaturallySpeaking and found that the included headset was very poor quality which resulted in Dragon NaturallySpeaking barely functioning. I decided to buy a quality headset. I chose the Andrea NC-185VM USB digital headset. Don't worry if you don't have a digital sound card, one is integrated into the cable of this headset. It cost about $50. Now Dragon almost always gets my speech right. I'm a student and write a lot of papers so Dragon has been an invaluable asset to my coursework. You may also want to consider the Andrea NC-185 analog version for about $30 if you don't have a USB port on your computer. If it is as good as the digital version, you should be very well satisfied.
