As far as I know, most people have more than one stroller. We have five. Different strollers serve different purposes and I don't think there is one stroller that can fit all your needs.

Here're our strollers:

1. Generic brand umbrella stroller: Most basic and lightest stroller. Cannot be reclined. We use it only for short distance walk or when too lazy too carry other heavier strollers. I don't think my little one sit comfortably inside.

2. Summer Infant 3D lite convenience stroller: This stroller can be reclined, which is important when you are going out long. Much more comfortable than the previous one, and still consider light with only around 12lbs. It has five point safety harness feature. We like to use this one for long travel because it is light and can be fully collapsed.

3. Britax b-agile: This comes with the travel system, which we used when our little ones were not ready to sit upright. It is about 17lbs if I remember correctly. It cannot be fully collapsed like the previous one, but my little ones could sit very comfortably inside.

4. BOB Flex jogging stroller: We use it when going out jogging. It provides good stability in bumpy roads or rough terrain and easy to maneuver. However it is heavy and therefore not easy to handle for my wife.

5. Britax b-agile double stroller: We bought this when we had the second child. It is a must for parents with two children around the same age.

From Amazon. I think it was USD 300 something, definitely less than 400.
