R4 is a better deal, as the Austrailian dollar gives a far better exchange rate than the Euro or British Pounds. I have the R2 on order simply because I loved the packaging of season 1 so much, and because I can't seem to find a reliable R4 e-tailer that doesn't charge my card right away. Amazon.co.uk is big enough that if there is a problem with my order, I know how to handle it.
