hi, have an uppababy cruz but looking for a more budget second pushchair and a good quality compatible car seat to store at family members' house for when we stay with them. baby is currently six weeks old and the car seat will need to last a year and the buggy ideally longer. the buggy just needs to be comfortable and compact and ideally good storage basket. like the look of the oyster gem and city minis but ideally something a bit cheaper - for the buggy and carseat would like to keep it around £250. any suggestions for a good buggy / carseat combo in this price bracket? thanks
