Eureka would be my choice as well...they make a good durable tent. We just upgraded the troop to new Eurekas.
Eureka Mountain Pass 3XTE - Camping Tents
The Timberlines, like Fishpart mentioned, are a scouting Standard. We have had ours for probably 20 years...and they are still in good usable condition...pretty solid tent.
Are you just going to camp in the summer? If you are going to do any Winter camping you really do want the vestibules on the tents.
Myself, I would put the kids in a seperate tent...more fun for everybody involved..when I was a kid the last thing I would want to do camping is sleep in a tent with me parents. Takes away that whole "lying awake and yapping for hours" dynamic that makes camping fun.
