I recently bought a PC to hook up to my TV, with the primary intention of using it for my kids to Skype with their grandparents, who live in another state. What I did not consider was that the typical computer microphone is only audible when you talk directly into it, and is useless when we are on the couch together hoping for a family conversation. Is anyone aware of a microphone which may be good for this? I am hoping to not spend too much. I have a laptop which we currently use, but the kids love the idea of seeing Grandma and Grandpa on TV.
