I just picked up a three person Mountain Hardward Lightpath this summer for going out with my two, but they have been at it for 5+ years. It is heavier than I wanted (6lbs!) but it fits us and I could afford it as opposed to some of the others. Have a great time getting your kids involved. I really enjoy taking mine out.
