I currently have a pliko pramette which I am using in pram mode. it also converts to a forward facing pushchair. Dd is six months old and is tiny for her age, so she still fits in the pram. She now prefers to sit upright, but I still really like having her facing me - especially now that she is more awake and I can chat to her as we walk along. She puts up with lying flat for now, but presumably I will have to swap her around before she gets too much bigger, or at least before she is able to sit up by herself and climb out 
so I would like a buggy with the option to sit upright but still be able to face me. It would also need to go on the bus occasionally and fit in the boot of a small car.
I don't have much spare cash so it would need to be very cheap -I'll almost certainly buy something second hand.
Does such a buggy exist? Or should I just stick with the pramette?
