Get a mouse with lots of extra buttons.
They come in insanely useful...I have one with two thumb buttons (Logitech MX510, to be exact...good mouse) and in PS I had medpacks on the front button and reload on the back. OMG what a difference it made.
For BF2 I'm going to have reload on that back on still, but probably do the the quick chat (the spotted, need ammo, etc) on the front.
Oh yes, it will be sweet.
SAW Troopers ftw!
