Setting up a backpacking tent in the rain is an acquired skill. Most tents, you put out the footprint, then the main tent body, assemble poles and hook tent to poles, followed by the rain fly. If it's raining and the tent is designed to allow it, you assemble poles, cover with rain fly, then you have a covered area to slide in footprint and can clip in the main tent (for the most part) in the dry.
A soggy tent is no fun.
On the other end of the spectrum, I seriously considered this setup from Lone Peak. With all the bells and whistles, it comes in around $8,500, but just 400 pounds.
