I have looked through previous comments on these...am looking at Emmaljunga Twin Cerox 360 (seems hideously expensive) or maybe a First Wheels City Twin. Will be used for 8 mo baby and 2 3/4 ds, for pushing up hill on school run. Storage not a problem and won't need to fold it for car (will live in house as ds walks everywhere except on sister's school run!) Does anyone have either of these please?
