Unfortunately, in Australia, the Denon DVD2500BT Blu-ray Transport is not for sale; rumours are that we may see it or a newer or revised version of it in February next year.
I purchased a Pioneer BDP-LX71 last week, and picture and sound quality are massively ahead of the Panasonic DMP-BD30 it replaced. However, even after the latest firmware update (version 1.17), it is still SLOW to load discs up! This applies to both Blu-ray discs and SD DVD's.
