Tandem travel systems

Tee

So I need to find a tandem travel system as when I give birth to my second my first will only be 18 months. The only ones I’ve found that I like are well out of my price range plus I just can’t justify dropping that much on a pram. Did think about secondhand but even then I’m looking at around £700!

I need to be able to attach my maxi Cosi to the pram, have the bassinet at the top where I can see it easily (I’m not a fan of them at the bottom as I’ll be wanting to keep an eye on baby) and I don’t like the ones where the toddler is sat basically on the floor by your feet. Can anyone recommend any reasonably priced travel systems that you’ve loved? I’m open to new brands and ones I’ve never heard of before

This is the travel system I would like it to be similar to
