Nobody is recommending you buy a $600 tent. What people are recommending is that you add lightweight to your desired list of features. And I agree with Daisy in that you have a fine list of tents, I stand by what I said: I think you can do better.

Case in point:

4 lbs and $130

A pound won't kill you, but unless you put some energy into keeping your pack weight low it will balloon on you. You are less likely to have a good time backpacking if your pack is heavy and less likely to keep the sport up.
