Don’t like the spacepacker myself – I had one a while back and if you are over 6ft you tend to sleep with a face full of inner tent fabric (you are inline with the pole).
My suggestion – Lightwave. They do an excellent range of tents which are light, spacious and damn robust. Got a T2 XT myself which gives a massive porch for storeage and cooking (if that is your bag) – you can even get mountain bikes in there, yet it weighs and packs smaller than my old Vaude MkIII by about 1/3. The non-XT version is smaller and lighter again.
They also do a semi-geodesic version for folk that way inclined, and the sister company Crux do a full on geodesic that weighs bolloxall.
