My macpac is 15 years old and still going strong, having been battered to bits. I have two other colleages with same tent, and same experience.
We have old Terra Nova Quasars and Ultra Quasars at work – strong in wind, but damn heavy and short on space (comparatively), we have Terra Nova Voyagers (lighter, but not as strong in winds and again short on space) staff also have a good number of Crux tents (light, superbly made, string, shame they pitch inner first) and we also run a number of Terra Nova Laser Competitions (sub 1kg!) which while being superlight and quite spacious can be a faff and are super, super light with little in the way of durability.
We just bought 8 Terra Nova Tri-spaces last week that seem good on space and in the wind we tried them in (only about 25mph), two very cheap but big Vango Beta 450's (better made than any of the Terra Nova tents above, just cheaper materials IMO), and have ordered and waiting for two new Macpac Minarets…
You pays for what you get IMO.
