We're planning on getting a Phil and Teds for when DC2 arrives, DD will be just turned 2.
I was going to go for the Classic as it's the cheapest, but then I was looking at the Vibe, and it has a few advantages, like you can fold it with the double attachment on. I dunno if that justifies the extra cost though...
Those of you with Phil and Teds, what model do you have? Is the Vibe the best one? What's different about the Sport?! Their website is pretty crap for comparing the pros and cons of each one. We'll have this pushchair for a long time so I don't mind spending more if it's worth it.
