Another pram to look at is the baby jogger city select - I love mine. Google it and check out all the seat configurations! It is not as wide as the strider but I think its comparable in weight, I'm really not too sure.
The downside to this pram is that everything is sold separately - second seat, bassinette, wind/rain/sun covers, snack tray etc.
The upsides are - able to have 1 or both kids facing in or out, can use a car capsule, huuuge basket underneath, easy to manouvere, smart looking pram, soo many other pluses I can't think of them. Definetely have a look, there are some great deals on eBay for new ones too!
