Have you considered Mountain Designs Sub Atomic range of tents:
http://www.mountaindesigns.com/index.cf ... goryID=124Kaon (sleeps 3, 2 in absolute luxury): 3.7sqm floor area; 2.7 max. weight, 2.45, min. weight).
Positron (sleeps 2, 1 in absolute luxury): 2.7sqm. floor area; 1.98 max. weight, 1.74 min. weight).
These tents are 4 season, free standing (effectively, require 2 pegs for sides) & extremely light.
They can be set-up with fly & inner integrated (fast-pitch).
They are also very, very roomy being about 1.2m+ high inside, enough to get changed without having to lie in the foetal position like a lot of tents;
think about being tent-bound for a day or two in a tent that you can't sit up in without your head touching the top of the tent or having to crane your head, very uncomfortable.
I am very fussy about my gear & have researched nearly every brand of tent extensively & these tick all the boxes (yes, Hilleberg look great tho very expensive).
if you ask for Amanda @ the Hobart store she might even give you a good deal? (being a good friend of mine I'm sure she won't mind me saying this

).
Hope this helps, i'm sure Amanda @ MD's would be more than happy to set them up in-store for you (I think a Positron is currently set up?).
(p.s. I currently have a Macpac Minaret which I have been very happy with; a little cramped for 2 people; you won't fit much else in them than 2 of you + sleeping gear, vestibule also a little small; it has been very comfortable as a solo tent, just too heavy for extended trips unfortunately + not free standing which I am wanting).
