Welcome to the best site on the net!
I like the AMK kits very much, but I add items to them. Also, if you're going to grab n go with an AMK kit, buy a water proof stuff sack to keep it in. The OR or Sea to Summit bags are just the ticket. I use a paint pen to put a couple of large white + on the bags after the extended kit is in the bag so it is easy to identify (if you use a light colored bag, maybe a red + would be more visible).
The Atwater Carey kits are good, too, and Campmor has their own version of them at respectable prices - often on sale. Same deal - stick in a water proof stuff sack (the type with a roll closure). They also need additional items.
Regards,
Tom
