Hi, I have a Rebel XTi and a couple of L series lenses. I wish my camera was built as well as the lenses. Anyways, I was wondering if anyone has experience using the XTi in harsh climates. I will be traveling later this year to Dubai, Egypt, India and Europe in the winter. Naturally I will be encountering hot, humid, and dusty conditions, as well as very cold temperatures. Buying a $3k pro body is not an option at this point, but I would consider a 30d. Don't shoot me, but I am also considering selling the Xti and L series lenses in exchange for the Nikon D200. It seems much more rugged than the semi-pro Canon offerings. Thanks in advance.
