L.D.
I have some version of a Maclaren double umbrella stroller and I LOVE it. When I was first looking, a friend suggested it, and it was so expensive I thought "Must be nice..." and went looking at others.
Other double strollers were SO HEAVY, didnt fit in my trunk, didnt push smoothly...
I got a Maclaren double off of craigslist for @ $70 and I love it. Its super easy to use, and lighter than my Chicco Trevi single stroller. Also, the seats recline, so I could bring my little one starting at @ 3-4 months (before that I used a single and carried the baby in a sling).
If I had to do it over again, I would have bought one new (and nicer looking) because they are definitely worth the money.
When you are taking two small children on an outing, the LAST thing you need to mess with is a cumbersome stroller.
