I think it really depends on what your planning on shooting. Over all if I'm going out of country I take my Nikon D90 with a 18mm-200mm lens and a tripod. If I stay in the US I use my Nikon D700 with a bunch of lens & tripod. Check out my travel pics at Smugmug, type in robeng.
Tell me how you would improve the pictures. Want you would do.

Just joined Ugly Hedgehog. I found it to be a great site for getting infomation. Been into hotography for a little over two years.
