I felt the same as you before I bit the bullet so to speak. I found a lady in my area who did demonstrations, she also has a shop. I went into her shop and she let me try some out on DD and she also explained how to use the different types etc.

Is there someone in Perth who does demos? Maybe go onto some websites and see if they have stockist close to you.

FWIW - I love Ittis, Greenkids and I am trying out Pop-ins.
