I've been thinking about a new tent, too. I used a Eureka Timberline copy, but switched to a Kelty Monarch 2 but that's a bit heavy.
I read
this article but thought most tents seemed kind of heavy.
I was looking for an REI Quarter Dome, but as mentioned they don't seem to make them any more. I'm considering the Half Dome:

The Nemo tents have a good reputation, and they seem quite light to me:
