You can still buy the CX7000ES and Google search works fine for me, but the CX7000ES region-free is only available at merchants in the USA which means costly shipping for you and although the units are dual voltage you'll still need plug adapters.
(package 2 is optional)
(slightly overpriced if you ask me)
Now those are the BDP-CX7000ES but am not sure the other one is still available region-free, a quick search here found nothing.
The region-free works as follows on this machine. By default all DVD's are region-free but for Blu-ray you have to select the region before switching on using the remote. However the mod doesn't convert PAL DVD's to NTSC and vice-versa, so either an adapter or a bi-standard TV is needed.
On the remote to activate the mod for Blu-ray: 1 for A and 2 for B (your area), then switch on. The default when the unit arrives is B according to the leaflet included. If you ever update the firmware you have to take care to switch the unit on to the right region mode for that firmware before updating.
Sony are noticeably slow at updating firmware, however, and I haven't seen one since I got my unit nearly a year ago. (20 is the latest for the USA/Canada, not sure what it is for UK etc.)
I found that the BDP-CX7000ES will handle 2 separate indices of disks, 1 for region A and 1 for region B, but inputting is rather fiddly and often needs to be repeated in both modes so you know which disk is which. I usually include a hint in the title manually so I know at a glance.
My only beefs at the machine are A) unlike earlier models there is no keyboard input socket so everything is keyed in on the remote and the screen, unless Gracenote got the info for you, which doesn't always happen (never happens for home-made disks) & B) You need a spare flash memory stick (8gb is ample) to plug in the back to allow the unit to remember disk data and for BD-Live content etc.
