if you are going abroad they get thrown about a bit so id get a cheap one, certainly wouldnt spend £150. we bought a tiny buggy from argos for £20 and have taken it on 6 hols so far in england/wales and are taking it to Majorca in Sept, its lightweight, small and doesnt matter if it gets ruined.
Would recommend the Petite Star Zia. It looks like this. Around £100-ish. Is a bit like the Quinny Zapp but is suitable from birth as the seat reclines. Very light, folds up really small, you can get a travel bag to carry it in, it has a raincover and small shopping basket underneath. For wintertime you can also get a cosytoes to go with it.
We got one of these when ds2 was 4 months (now 14 months) and it is now our buggy for keeping in the car as it takes up very little boot space.
Would advise shopping around a bit as you can get quite good deals sometimes.
