We have a Baby Jogger (City Select model because twins 🙄) and it's amazing. So light, smooth to push and turns on a sixpence. Absolute pleasure to use.
We bought a secondhand iCandy Apple on EBay with DS1 and I really regretted it. It pulled to one side and was heavy.
Nothing against iCandy at all but I'm just sharing this to illustrate that your travel system / pram is a really important purchase and I now feel it's worth spending the money if you possibly can, for excellent engineering and ergonomics, simply because the damn thing is your gateway to having any kind of life outside the house when the DC arrives. Unless you use a sling or carrier of course, but I tried several and just couldn't get on with these when I had DS1 (and no good with twins obvs).
When we were looking for a travel system back when I was pregnant for the first time, we asked for recommendations from the lady in Mothercare and she said 'Well it depends what you want - it has to fit with your life'.
That didn't help much because my life to that point had been blithely working full-time, going out for cocktails, wandering around tiny tea shops in random locations with DH, sleeping in at the weekends and dancing at sweaty clubs with my gay best friend.
I had a suspicion that nothing about the logistics of my life would apply any more and should therefore have no bearing on my travel system choice. And you know what? I WAS RIGHT. 😄
If I could go back in time and advise myself, I would drop to my knees and implore pregnant clueless me to just spend the highest figure we could say out loud without flinching on whatever make and model would be the lightest, easiest to fold, most compact and nifty to steer. i.e. what would make my life easy.
Not sure if that helps any. Good luck!
