It's been aaaages since I had my DC (well, 10, 7 and 5) and I was very happy with my M & P X Cel system. I liked the solidness and the fact it had a proper pram type attachment. It was very bulky though and I don't think you can get similar anymore, everything looks pretty flimsy and foldy. I broke my chassis and the other bits are at the backs of garages and lofts and I think it's time anyway to get something more updated.
My wish list is:
off road ability
Solid
System which takes car seat/pram attachment etc.
somewhat foldable (but I don't have space problems or use buses/trains much so it doesn't have to fit into my pocket or anything!)
And if im veeeery fussy, a traditional material (i.e tweedy)
It doesn't matter if it's not the height of fashion, or 2nd hand (infact DH wants to buy 2nd hand and I see his point, so an old model is fine)
I really am clueless about all of these things .... thanks mn :)
