Really, my dreams wedding coordinator said something along the same lines.
The story went like this.....When my WC told me the price of thier DJ I nearly fell out of chair at work. I emailed her back with some of the prices I saw on the forum and she said that they highly recoomended DJ Ricardo (booked him) and she did not recommend the other 2 (DJ Mirajes and DJ Funcle Ron). She said that is was a far too important part of the wedding to take any chances. So basically steering me away from him.
At first I was a little annyed but then I realized that she works on god knows how many weddings per year, per month, etc. and she is only looking for me to have the best experience possible, and would not lead me in a bad direction.
And you do need a good DJ with good equipment. Someone who can feel out the crowd and make sure the party gets started.
My step mom reminded me of a wedding recently that she went to where they had a bad DJ, scratchy sounding speakers, and he was just awkward and hardly anyone was dancing and many guests left right after cake.
So I sucked it up and busted my budget to not have to worry about it.
Okay that was a little bit of a rant Sorry
