Yappermouse $49.95 at Deals Direct
I have not been able to find a price on this anywhere else (not that I am surprised) but thought I would mention it for interest only.
You can of course buy a cheap basic mouse and cheap USB phone for about $50-60 if you wanted to be traditional. But this is a good idea if space is at a premium. Though I wonder if people might think you a bit odd when you start talking into your vibrating mouse!
