I found out about Phil & Teds on a research trip to Right Start, where I was tracking down a decent-looking double stroller we'd seen in the park. The saleswoman said, "Have you seen Phil & Teds? We sell out every shipment we get within days." I quickly forgot about the other rig I'd come to see.
Generally, I'm not a fan of the three-wheel thing, but Phil & Teds ingenious e^3 buggy just might change my mind. These off-road strollers are from New Zealand--and proud of it. I can just imagine these hiking Kiwis, determined not to let the arrival of a kid keep them cooped up.
Anyway, what's most striking about the P&T e^3 is the adaptability. The single reclines for a newborn, sure. But it also converts from single to double stroller without turning into a sidewalk-clearing tank. Of course, to make that work, it relegates one child to staring at the other's ass all day. Be sure to avoid favoritism and rotate the kids frequently.
The single is $US 357 on the site; the double is $US 428. The site also lists retailers, but I don't think I've ever seen one of these in person.
