I have the Graco Quatro. It is a bit heavy, but accesories are awesome both for when the baby is in the infant seat and for when they start sitting in the stroller by themselves. It has cup and snack holders for both seats, double cup holders for the adults, and a HUGE basket!!! We took it to Disneyland and it was just awesome.
the ONLY thing is that it is a bit heavy, but for the ride quality for the kids....it's great.
