looking for reliable tents

Roy:

Your link didn’t work. But it seems like a lot of the pop up / self erecting tents are on the heavy side.

In contrast, there are many dome tents that are much lighter — and pretty darn easy to set up. If light weight is high on your priority, take a look at Big Agnes tents. For lower price (but slightly higher weight although still reasonably light) — take a look at the REI Quarter Dome.

Kelty Tents are well made, durable, and reliable which make for great kids tents. The Kelty Teton 2 is easy to setup and although not the lightest 2 person tent isn't too bad with a weight in the mid-4lb range.
The sale price is nice too at under $100 with free shipping at Bob Ward's.

The Kelty Salida 2 looks like it might be a good option. Pretty low weight for a mass produced tent 2 person tent (3lbs 15oz) and plenty of room for two kids. It gets high marks from Backpacker FWIW. They generally retail for under $150.00.
