Inthebeewitched - highly recommend the bjcm! If u get the bassinet it is more than sufficient as a proper system, the adapters that come with the bassinet fit your maxi cosi and its so easy, we are still using ours 2.5 yrs on, and it has suited every occasion. Lots of friends had bugaboo, quinny systems then swapped to a pushchair where as we have had the bjcm the whole time.
I unclipped the pushchair part from the frame for the first 6 months so we had a really lovely looking pram with either the bassinet on or the car seat and it worked a treat, then just popped the buggy bit back on when DS was ready to go into the buggy.
Such a light buggy, easy to fold and travel with. Customer service is fab too and they send out a replacement part no questions asked the following day when we had a minor problem.
I clearly think everyone should have a baby jogger - I swear I don't work for them
