Depends mainly on what car you drive, and how much you've got to spend.
We've got a Freelander and started off with a Mamas and Papas Ultima
Which came with a car seat, stand, stroller, pram etc. I think we got a deal for £550 ish. It was great except the wheels we got are fixed so steering awkward and it is massively bulky even when folded. AND you get done for another £135 for the ISOFIX seat base, which although not totally necessary, is loads more secure than the seatbelt only fitting.
So we then got a Quinny Buzz stroller. Which is much better, still bulky but less so than the M&P one.
As your child gets bigger, you don't need the pram base etc. so maybe change to a fold up stroller?
Treat it like buying a car, some brands are Fords, some are Skoda's, some are Mercs.... how much they want should give you a clue how they see themselves.
My little girl turns 1 tomorrow. Can't believe how fast its gone......
Crikey the worlds insane! You guys nearly spend as much on a child as I do on my Parson Russell Terrier
