Take the new NIKON D300 camera, several good lenses and several memory cards for it. Or better yet the D3 true professional digital camera. Now if you're more of a CANON guy then take their awesome Canon EOS-1Ds Mark III SLR along with the goodies for it. We want lots of good pictures of your trip.
By the way I'm teasing you. Any good digital camera will be more than fine for taking and posting forum pictures when you get home. You don't need to go all out with high end professional equipment. The main part is for all of you to have fun.
