Why don't JB Hifi put the model numbers on the internet?
No prob with things like PS3, you can tell what that is.
But, with receivers, you have no idea what model they are trying to flog....
eg,
http://www.jbhifi.co.nz/jb-hi-fi-home-audio/receiver/onkyo/7-2-channel-av-receiver-sku-16319/
THey only print the SKU which is some internal jbhifi code (or a US zip code :) )
