I couldn't be bothered to keybind until I invested in a $70 Razer Naga.. It is spectacular and more than sufficient for all keybinding needs. Importanly, it makes the process of setting up and using keybinds extremely simple even for the dexterity challenged people like myself. Also lazy, again like myself.
I use a Razer Naga mouse for MMOs.
I move with both my mouse and my WASD depending on the situation.
