I don't know much about the SUB bikes but they do look alright. There's only one chickie from brissie on TE that has one & you could always send her a message? (light_sabre..)
If you don't get a response, try http://www.bicycles.net.au/forums/index.php for a local perspective. I know there's a few Canberra ladies over there that might be able to help.
