hi Y., i have the valco double, it is wonderful. it is expensive and it is big, but it folds easily, steers with one hand, and i put my 3 kids in it, my 11 month old sits alone, and my 5 year old and almost 3 year old sit together, one behind the other. when the baby was in the carseat, it clicked right into an adaptor that they sell for it, that was the best! and i still put all 3 in! if you walk a lot, especially outdoors, like grass, gravel, etc, it is great. we live in this thing, i wouldnt trade it for anything. its just very heavy. i fold it right into the back of my van without lifting it. if i didnt have a van, or if i had to bring it up and down stairs and i had to lift it, i wouldnt use it. check it out.
