I'd have to echo what you've heard here, go with the Coleman tent. I have found their gear to be a little heavy, but, well constructed for the money. If you're going to spend a lot of money for lightweight, high quality backpacking gear, you can find better equipment, but, you're paying a real premium.
I'm assuming when you say "family camping", you're talking about basically tailgating, right? Drive up to the site, empty out half the house from the back of the SUV?

We have a big Coleman family tent that we call "the condo". It's for when my wife comes camping with us. We've had it for over 10 years now. It doesn't get real heavy use, but, multiple trips a year certainly. Still sheds the rain fine and keeps the bugs out. Do make sure you seal the seams of your new tent. That's something people forget, until the first rainstorm.

My son and I mostly do backpacking, so we opt for smaller, lighter gear. I like my Sierra Designs 2-man for backpacking, although we also have one of Coleman's eXponent line of tents that's suitable for backpacking, and is really pretty competitive with far more expensive models from MSR, North Face, etc. We recommend all sorts of Coleman gear to the new scouts joining the troop. (And the Coleman outlet gives Scouts and Scouters 20% off their gear when you show your BSA card. (even off sale prices!)

Have fun camping!
