Michael, I would definately recommend YIV, considering that the quality of your voice takes a major role when people make that ever important "first impression". In my opinion, some of the tips/excercises in the first half of the first CD (There are two CD's) are worth the price. If your interested in improving your voice, I'd also recommend "Talk To Win" by Lillian Glass. About $15 at most bookstores.
