I have a strider plus 4, and its been a great pram for having 2 close together. I do take the top seat of to fit in the car, but normally leave the 2nd seat on, and its never been an issue having a 2part fold as its so easy. Its actually easier to take the main seat off than the 2nd.

Here are my pro's/our reasons for choosing it:
reversible front seat
both seats recline
good size shopping basket, even with #2.
accessories came with it.
I like the height of the seat. Some prams, the baby seems so low down.

Con's
heavy
wide (like a pp, Kmart always seems to be an issue, but thats about it)
ours has a bit of a wobble, but I'm not sure if thats because I had DD in the 2nd seat after she went past the weight limit. It is still fine in single mode though.

We have the kingfisher, and it is looking quite grubby. Trouble is, the fabric doesn't come completly off the frame to put it in the washing machine, so I'm going to have to give it a good scrub. I wish I had got pram liners, which would solve that issue.

Apart from the wobble, I do have a couple of issues with the frame, but this is only recent and its getting close to 2years old, and has been used practically everyday. But otherwise, I do love it.
