I found the 2009 version of Phil and Ted sport with double seat for $100. Is this a good deal? I tried out a phil and teds stroller (not sport) at toys r us yesterday and loved it. Right now I have just my son but we plan on more kids. We are currently trying to get pregnant so my son will probably be around 3 years old when the next child comes along. Is this a good stroller for that age gap or should I be looking for a sit and stand?
