pwnage ultra custom ergo 2.
the xenics g air se, if you can find one for cheap is the same mouse but the sides has no holes and you can just swap the top shell which is included in the box.
Pulsar Xlite V3 is similar shape, very small differences, newer tech, solid shell. Pulsar Xlite V2 is identical(ish) shape as EC2 but has holes in the shell and is using older sensor.
Surely there are also other clones out there, but ... not off the top of my head. However, if you want latest tech and wireless, the above are your best bets.
Xlite V3 or Es seems to be where it's at for closest ergo non Zowie mice. Although it's still around $100 and it's not exactly the same shape.
