Cheapest, most lightweight rearfacing pushchair

[QueenOfFlamingEverything]

Oh and preferably with biggish wheels too...

Does such a thing exist ??

Not with big wheels, but I'm someone will suggest the Bee+ and the Loola.

(big wheels are hard to come by...but they're a life-saver on the snow and sand. unfortunately, you can only get them on heavier pushchairs. they may be worth considering, especially if the seat is easy to pop off to get the thing into your boot)
