In reply to UKC Gear: My group used one of these on expedition to Peru last year, and they were good tents.
Easier to put up than a Quasar, due to the poles clipping rather than sliding through sleeves, and very spacious and very strong.
We had condensation problems, which the new vents may help (on the old model you had to leave the doors partially open to get a through-flow).
Very heavy though. If we had been carrying them rather than using ponies for our kit, we may not have been so keen!
