Hi A.,
Your question is timely for me too--I'm 37 weeks pregnant, and have a 21 month old and have also been in the market for a double stroller and have appreciated reading the 13 previous replies.
I have the Phil & Teds E3 stroller and have loved it for my son--it's very maneuverable, comfortable for him, and folds pretty easily. We bought the second seat attachment and had planned on having this stroller straight through out second child--but I have second thoughts about it, which is why I'm looking for a different double stroller. Here's our problem(s):
(1) You can't use a car seat when you have 2 children in it, and I really like not having to wake up the baby or do unnecessary moving, so I want a double stroller that can accommodate an infant car seat.
(2) When using the stroller for 2 kiddies, th infant seat is a fully reclined "bed" that is situated under the toddler seat. So the baby gets a view of the back of the seat above him or her, instead of the view of the clear blue sky like my firstborn had. This didn't bother me when I first bought it, but it does now. And once both kiddies are sitting upright, the one in the back has to look to the left or right to see out into the world. Looking ahead again yields a view of the back of brother or sister.
I have a friend who is a big pedestrian and had little use for the car seat--she loves this stroller and has no complaints about its use for 2 kids. But now I'm looking for a double that is also a jogger, because I also like to walk a lot and our town has crappy sidewalks--so a jogger is much easier to use on our streets & sidewalks. Problem is, the only ones on the market that also accommodate a car seat are tre expensive! The BOB, the Mountain Buggy, the Baby Jogger, the Valco--all over $400 new. the Phil & Teds wasn't a bank-breaker, but it was not cheap either--so I'm having trouble reconciling spending this much on a new double stroller when I've already got one in my house, just not one I really want to use now!
Good luck to you and thanks for posting this so I vicariously learned too--it sounds like that Joovey Sit N Stand or the Baby Trend Sit N Stand might be something to think about.
