we have the strider plus 4, so can't help with the questions about the 3-wheel version...however, I love the strider plus. It is a bit wide but at our local supermarket, there is only 2 checkouts that it doesn't fit through. Yep, it probably wouldn't fit in the smaller gift shops, but then I had trouble with the maclaren in one the other day! It is heavy with 13kg DD and 7kg DS, but then any double would be. The advantage of this over a side by side for us, was that it fitted in the car, and on the days when I don't have DD, I'm not left without a pram.

Babyluv - we didn't bother with the capsule, partly because we were offered a diff capsule by a friend, and also, DD only lasted till about 7wks in a capsule when we traded it in for a reversible, so didn't want to pay for a capsule that we might not have used. As it turned out, DS didn't like the pram for the 1st 12 weeks, so was always in a sling anyway.
