@KatieGlo also think about where you will use it. Where I live has cobbled streets and we would also off road a lot so we needed something which could handle both. We got an I-candy peach but second hand - a bit bulky but was really good for us though a pain to fly with as was a 2-piece.
Benefit of it was that it also fir the maxi cosi pebble plus car seat using adapters. And if you’re going to have babies close together then you can change it into a double (though we’ve not figured out whether our DC is too big to do this yet).
Def think about how much room it takes up in boot of car and how easy it is to assemble/disassemble. Width is another consideration if you shop a lot as some are too wide for doorways(!)
I have to admit I was a bit envious of other mums who had nice new expensive prams as we had been more practical and decided it was pointless spending upwards of£1k on a pram which was going to get trashed in baby sick, milk and battered travelling (as we travel a lot) and that soon wore off. We bought from someone I vaguely knew (knew her sister) and paid £350 which included base, lie flat, 2 x seats, rain cover, foootmuff and 2 x adapters.
Also next to me is fab we did buy that new and will use for number 2. We had a separate cot in lounge which friend had given us and just bought a new mattress. That was invaluable as we kept DC in there when napping in day and until we went to bed as they’re not meant to be in a separate room to you until 6 months
