We had the 3d with our first baby. It has pros and cons as they all do. The car seat is very heavy and the pram is too so when using as a travel system its VERY heavy!
Its lovely to look at and had adjustable handles, it can be folded up in pram mode with the cot still attached which is a bonus but the pram mode is quite small and only last till there about 12 weeks and my dd was quite small.
The basket is a bit useless :lol:
I think you will find fault with all prams though.. go and test drive it
