S.Z.
I have a different suggestion than others. I bought the Graco Tour Duo. Loved that I could pack everything in it. I had a safe seat that matched but the Safeseat did not seem to fit in right. So we bought a coordinating Snugride. That worked great. Although I liked the Tour Duo, we didn't use it often b/c it is heavy & bulky. I am not weak, but it wasn't worth the hassle to take in & out just to run into the store.
It is far better than the standard Duo Glider. But we did sell ours on Craigslist after 3-4 months.
I bought the Chico Extreme Trevi double side-by-side stroller. I love it! It folds as small as two umbrella strollers. Fits behind our 3rd row that is about 11 inches.
It is a better version of the Maclaren Twin Techno for half the cost. If you email me, I'll tell you why I think that... I did a lot of homework. =)
One thing, I bought this when my daughter was 6-7 months old, and I can't remember if it had attachment for a car seat.
Hope my suggestion helps!
