Ok so I have been researching all day and I'm totally stuck!

I want to switch to MCN's but I don't know which brand to go with, so I'm asking for some help.

THis is what I want from the nappy:
One size fits all.
All in one.
Good fit.

Please please please anyone with experience can you please weigh in on this thread cause I'm sick of paying out $40 a fortnight for nappies!!!
