Six months ago we purchased the Graco Metro Lite LX Stroller for our granddaughter. I had to assemble the stroller and it was not that difficult, We do think that it is very flexible in that you can use just the stroller or with the infant seat. There are 2 things that we do not like: 1. the stroller is a bit difficult to fold down: 2. if using without infant seat you can not see the baby to well.
