I use Truecrypt full-disk encryption on a disposable laptop which is imaged before I travel. I take a prepaid cellphone that has a factory firmware erase and a fresh SIM card when I travel.

Just give me receipts for what you take .. and have fun with AES256 (and I know how to generate key entropy .. it's not the dog's name you morons). Just don't make me stand there for 4 hours arguing about it. NO, YOU CAN'T HAVE THE PASSWORD.

Don't travel with anything you aren't prepared to loose.
