I bought this camera 3 weeks ago for 448.99AUD at t-dimension because they seem to be the most trustworthy of all the grey importers.
Shipping was quick (ordered Monday afternoon and received in Brisbane area Thursday via DHL Express).
The new price seems to be the best one i could find especially when you consider their reputation and that shipping is free.
The camera itself is really good and I had lots of fun playing around with the DSLR like controls and manual mode (I was even able to get some decent panning shots).
dpreview finished their review this week as well: http://www.dpreview.com/reviews/canon-powershot-g15
Why won't they accept my 28 Degrees MasterCard? I really want to buy this as it's an awesome deal.
