Mad Catz Interactive (Saitek) has launched a batch of high end Cyborg gaming mice which will start shipping in Q2 of this year. For the first time ever on a mouse, the main contact points between the gamer's hand and the mouse are adjustable allowing a customized grip preference. Cyborg states that they are the most comfortable gaming mice around, and I am sure this is true, but this is more of a desk candy thing, looks freaking cool.
The top of the line Cyberog R.A.T. gaming mouse will set you back about $130 and comes with rechargeable lithium ion batteries, a 5600dpi laser, removable weights, and is wireless.
