With regard to negatives of BGs, I find microfibre inserts a bit naff, so I use different inserts, which pushes up the over all price of the nappy and leaves me with a pile of unused MF inserts.
And, if the environment is a big driving factor in your cloth use you should also consider the airmiles of the nappies, they're made in the US so they have to travel a long way to get to you. There are lots of UK or other EU made nappies that have to travel a much shorter distance.
You could try Totsbots. They have just re-released the Easy fit AIO (I didn't get on with the originals but am willing to give them another try....... beacuse they're really pretty ) They're made in Scotland I believe.
