for this price, I will most certainly suggest a non-reversible, world-facing-only pushchair. That will be less expensive and also more spacious for your baby. The first that came to mind was a Britax B-Motion Plus, which, I know, is heavier than you wanted. BUT it will last you even for a LARGE toddler and will tackle bad pavements as well.
Another model I thought of would be a TFK Dot 2 or a Gesslein S4 - these are quality stroller that I think you'd like if you'll be able to get your hands on those.
Lastly, I'll mention a Valco Snap 4 Sport with inflatable wheels, or maybe the better version, Valco Snap Sport Trend. I was also thinking about the Petite&Mars Street+ with Air wheels or the Petite&Mars Royal but they're also not available everywhere.
Remember that you always need to go for one, two main priorities when choosing a stroller and you cannot get cheap, lightweight, roomy, and foldable all at the same time. You either get all-terrain or light & compact, and either small or spacious... And the affordability makes the choice even narrower.
