So, those of you with more experience: Should we get a double stroller? If so, which one?
If I had an extra $600 lying around, my dream stroller is this one:
But, since I can't justify paying that much for a stroller, and I can't find it on sale anywhere, I would have to go with a backup. A very similar stroller, the EasyWalker Duo, can be found on sale if you're not choosy about color. I think I like the side-by-sides much better than the tandem ones, since those seem to feel like driving a long bus. The Duo is nice because it is narrower than many side-by-sides, and more substantial than some of the lightweight umbrella strollers.

I've also thought about a sit-and-stand, like the Joovy below. I think Hayden would enjoy the freedom, though it doesn't seem as practical for walks/jogging.
But, what do I know?! I'd love some advice.
