The Coleman does look the business, however I can't help but think it's a bit big. Between that and a four man tent I think we'd take up more than what would be considered reasonable for a small team at an event ❓
trail_rat, those look really good and if the longevity is as you say then very cost effective. The fact there are spares available helps too.
The E-Z Up certainly looks like the benchmark however if I'm honest I could only justify a cost of ownership of circ. £50 per year on something that would be as infrequently used as a gazebo and I'd probably be dead before I felt I got my moneys worth out of the Eclipse II 😀
