I let my subscription run its course with no results. The status, for me, never changed from my original post. I don't know what "extra's" you'll get from agency representation, as most of the auditions I've seen have come to me first from another agency, so VO Planet offers them up anyway and has little exclusivity, or the audition so esoteric in its requirements, they have to throw a broad net out in order to find a VO talent that fits.
I could be wrong. These are just my observations. V123, andVoices.com for me, has paid their subscription fee many times over. VOPlanet...again for me, a middle class, middle age, male VO talent.. was lost money.
