IPEVO's TR-10 speakerphone makes nice with iChat
Seems like there's a VoIP device for every temperament -- you can go supa classy, or you can try to be as bland as possible, but most of them are intended for Skype. Not IPEVO's TR-10, though; it's designed for iChat, and it does VoIP with support for four-way conferencing as both a speakerphone and a handset. If geeky rebel radio is your thing, it records podcasts in tandem with GarageBand, too -- all IPEVO asks is that you fork over $79.90 before you start living the iLife with Bruce Willis.
