The Deathadder is the one I am leaning on. I will see if Best Buy will let me try one out. I use my palm so this should work well correct? At least the tech at OCZ thought so and those were the two he thought would work best.
Do you know of any pictures with the Vandal switches installed in a case besides Performance PC?
I can't say... depends on the size of your hand. I am pretty sure they have them at best buy so you can feel it out.
heres a thread with the vandal switches installed.
