Razer Mamba and Razer Orochi are wireless (you can also use them wired)? The Mamba is a bit big, but Orochi might be a good one for you since it's compact:
http://www.razerzone.com/gaming-mice/razer-orochiI actually can't vouch for it since I've never tried it, but it has the same sensor as the other current Razer mice, so it can't be too bad!
Personally, I might be a bit old-fashioned, but I liked having wired mice. And Razer's wires are hella sexy

The Death Adder has been around for a while, so the design changed a little bit. Only one version of it is currently in production though. The only real differences in it compared to my old one are the sensor, rubber grip on the side (instead of plastic), and green LED instead of blue.
Anyway, pictures.??

From the other side:

As you can see, they look really similar. The 2013 model is a little bigger, has that green LED, and is rubbery on the sides. Same shape though.
Along with two other mice: Razer Diamondback (bottom right) and the veteran Logitech M510 (bottom left)? The current M510 design is really different from the old one though, and Diamondback has long been out of production.

The M510 is literally 10 years old and still works like a champ, but the wheel has got really creaky, which is why I replaced it.
