Are you kidding...you do realize that the top consultants are tight with adcoms. A lot of former adcoms go to work for them since they probably get a hefty pay raise. Its all a scam, they are just "networking" with the consultants. Heck, sandy made a post about having a meeting with other elite consultants at Tuck with adcoms from top schools discussing the state of b-school admissions.
Many of the people who use consultants have lots money and come from stellar backgrounds, they are getting into schools anyways. It just makes it easier for the schools to ensure these people dont slip through the cracks and get dinged.
That said there is a huge drop off between the elite consultants and the rest. Not in price but in what they really can tell you. However, if you hire sandy's company chances are unless you are some superstar you are getting pawned off on one of his minions. He is too busy posting on BW anyways for your paltry 4K or whatever it is to really get him involved.
I hear that Joe Smith cat is a god with applications.
