Thought I'd give you a quick update after the should I buy a hugabub? thread 
I won the one on ebay, and it came today. Its like origami with fabric
. Finally sussed one position, and DS is asleep in it at the moment. It seems much more comfy so far than my ring sling (although I've only been round the house in it).
Think it was a good move (even if Serenity did trick me into it
)
