I found an old thread on this but a number of years out of date and both buggies have been updated recently. Looking to buy one or the other for 2 yr old. We need something more lightweight and easy fold as he no longer sits happily in his BJCN on bus/train. I'm pregnant with #2 so we'll get decent use from it. The quest is cheaper (in JL at the mo) and advantage looks like it'll take a car seat where techno won't which will be useful for #2. But everyone seems to love the techno more. Any thoughts?
