I have several, the main one I keep in the car. I like pre-made kits that I modify and add stuff too, and I like bigger cases which you can buy anywhere and are pretty inexpensive, then fill em up!
one cool thing I like in my kits is a SAK (swiss army knife) and a new bic lighter and water-proof paper and writing stuff.
my gawd you can spend a lot filling them kits up! doh
