As with anything that goes on at an event, there is a cost for providing a quailty sevice. Now I'm not saying not to shop around. Please DO!
Get quotes from as many as you can. This will help you with your budget and booking the right dj for the event.
Look at the content on the DJ's website, are they informing you, giving you information that you can use, or does the whole website read like a sales pitch.
Most website's are designed with a lot of flash but no content. The content on a website will tell you a lot about the service and their understanding of events.
