If you want another wireless in the shape of the MX1000 the closest you'll get is the Razer Mamba. It's in the same shape of the DeathAdder mostly but can be wired or wireless. It's extremely expensive though at $130 bucks.
I've heard good things about the G9x, but I couldn't go that route. The MX1000 and G7 spoiled me. I can't go back to a wired mouse.
