well done, should feel now as if it was meant to work like this in the first place. :)

How long did it take and what tools have you used?

around 3h, DREMEL tool and soldering iron

Ez mod you just need a mouse to fit DA pcb and same scroll wheel mechanism.

lol ye, razer should start selling only the PCB.

I did a g9x mod with a shape very similiar to this some time ago. The mouse was from "Hama keyboard mouse set (RF-2000)". Its the only shape which i think is even better as G1,mx300 shape.
