Open Question: Which backpacking tent to purchase?

I'm looking for a good all-round backpacking tent for 3-4 people, me (14 yrs. old), my 11 yr old brother, the occasional friend, and possibly later on my 8 yr. old brother.

Weight isn't to much of a big deal, as I'd prefer durability to weight, and to a lesser extent space. I'd prefer a 4 season tent if it is suitable for summer use. Also I'd like a double-walled tent, with closable windows (mesh). The reason for closable windows is that I want to be able to control the air flow. If a tent without closable windows would stay warm enough I would consider it, though always having a breeze based on the wind would be an annoyance.

Some brands I've looked at are Hilleberg, North Face, Stephenson (Warmlite), Black Diamond, among many others. This tent needs to last me a long time, as I'm not going to get a second tent anytime soon. Money isn't really an issue, as there are plenty of bargains I can find out there. The tent will be used in the little Rocky Mts., Montana.

Thank you for your time.
