sorry for the brief reply - I was on my way out when I spotted your post.
We have the pre-cursor to the Volo and it's a fab stroller - superb for an older child who doesn't need to lie flat for a nap.
For a younger child we have the Chicco 2003 (also called Touring), which is similiar to the Pliko, except here in the UK it's a lot cheaper, not sure how prices compare over there.
That's a great stroller but it's a lot more expensive and it's bigger and heavier when folded. My dd (age 1) sleeps like a dream in it though, and DD (Age nearly 6) can ride in it too, although I discourage that, but it is certainly big and strong enough
