I was looking between the Bye-bye Buggy and the Angeles Runabout. I found two daycare centers that had purchased both. They said the bye-bye buggy wasn't easy to turn, had to take wide turns AND that the seat belts (and all parts) were built in so when they broke they couldn't replace them because the stroller is all one piece. Because of this they purchased the Angeles Runabout and preferred that model. I ended up buying the 6 seater Angeles Runabout and LOVE it. It does get heavy to push uphill but it's smooth and the kids love going it it. I also used it in the snow this winter.
I'm not sure where you're located but I'm in Ottawa and found it here way cheaper than anywhere else.
