i love the silvercross 3d too, i would buy it over the m&p pramette, its much sturdier. my daughter is 18 months and i find it absolutley fine with her in it. i cna easily lift it in and out of the car boot and up and down kerbs.
fab value of rmoney too as comes with all the accessories.
phil nad teds is good if you are thinking ofhaivng another one asap after the first as can change to a double easily. however i don't like using it as a single for a newborn even with the cocoon as its quite low down and swings a fair bit, whihc is a shame as the p&t is a fab pram.
you say micralite do you mean the new toro? if so this is great too, i haven't used it with the carrycot as my daughter is too big for the carrycot, i used the origional micralite wiht the carrycot but it was tiny, however it looks like the toro one is much bigger. the toro seat unit is fab, excellent recline, great hood, nice apron/cover thing and comfy seat. good value for money only downside is no rear facing once out of carrycot. fab colours too!
bugaboo is my fave. i have had a cameloen since lucy was born, i had a frog as well and only sold it as i had the cameleon. the carrycot is a bit basic and most peopel don't find it lasts to the 6 months its says and the seat unit is not supposed to be used under 6 months, however lots of people do use them before.
i would say if you are going to continue ot use the one buggy form birth through to toddlerhood then go for the bugaboo as it will last and last, but if you plan on changing quickly for a lightweight maclaren or the likes then go for the silvercross 3d or m&p pliko pramette if you prefer it.
i have to say i prefer the silver cross ventura car seta to the m&p primo viaggio too, the m&p is too upright and babies head lolls forward making them very cramped and uncomfortable.
unfortunatley i am one of those peopel who love my buggies too much and have probably test driven most of them out there, so if theres any others then just ask i will try and answer for you.
oh p.s m&p ziko herbie, whilst it looks fab is heavy and bulky and awkward to use, i love the design and colours but wouldn't recommend buying one!
