Paul wants to start podcasting and he heard about the MicMe, which would let him record through his iPhone. Leo says that it does an interesting thing. It records to the mic first and then uploads it to the phone. It's also not cheap at $500.
Leo says Laura needs a camera that accepts external audio like the Canon Vixia. She can then plug the mic in. If Laura needs wireless, then the price goes up, and cheap wireless is a bad idea. Leo uses Lectrosonics for wireless microphones. They're very pricey ($1000 per mic), plus the receivers, plus the mics.
