Skysue, It doesn't have to be the Phil and Teds. It's just I have been using that for long time and I feel comfortable and easy to push thats all. If I find something similar to that I'm OK. to buy that too. I'm not really a fan of side by side buggies.

I have just looked at the links you pasted on here. But I think $350 for a second hand and for an old version of Phil and Teds is too much. New ones are around $50- 70 over that price(well last time I checked). If I'm willing to spend $350 on an old version second hand I might as well spend bit more to get a brand new one.

How much is a reasonable price for a second hand front to back strollers?

And thank you Judy I'm going to search now.
