Any preferences on Mice?

I use a Mad Catz R.A.T 5 because of the adjustability and shortcut buttons + horizontal scroll

I love most trends around js, because often they're thoroughly thought through (not always) and make things easier.. but why the fucking fuck do all the js coding standards use 2 SPACES. Now this isn't intended to be a tabs-vs-spaces rampage rant. But this decision against tabs is like saying yes to a 50ct pencil instead of 100 dollars.
