You are significantly limited by availability. HDR-FOX can be got if you try hard enough, otherwise you will end up with a HDR-2000T by default. However, if you want to know about the 2000, look in the right section of the forum where it is already being discussed.
If your aerial can pick up more than 1 transmitter then the HDR-FOX T2 auto-tuning can cope, but with the HDR-2000T you may need to resort to manual tuning; The HDR-FOX T2 can be easier to set up as the RF out will passthrough the aerial signal both when it switched on and when it is standby; There are NO reports of 'Failure to record due to loss of power' with the HDR-FOX T2, (there are reports of such recording failures with the other one); Manually started SD recordings on the HDR-FOX T2 can always be exported OK on the HDR-FOX T2; The HDR-FOX T2 handles subtitles on the new HD channels better; The HDR-FOX T2 handles 4:3 TVs a lot better; The remote has more buttons and so some functions are more easily accessible and therefore can be easier to make work; The remote has more buttons and some of the additional ones add functionality only available on the HDR-FOX T2; The HDR-FOX T2 can work an amplifier and a DVD player/recorder as well as the PVR and the TV; The HDR-FOX T2 has a display unit on the front so its easier to see what it is doing (but it is very dim and may not always be visable).
Being newer the HDR-2000T: can handle IPTV channels OK; may well have software updates for longer and perhaps some of them will fix the additional issues it has; Additionally the HDR-2000T has less buttons on the remote and therefore can be less daunting to make it work.
Thanks for the links, I was looking for one fast and didn't want to wait for delivery, I have used Humax direct before and would have no hesitation doing so again.
I actually went to Richer sounds after checking stock online but they had nothing available (should always ring first) so I got the 2000T new with 5 yr warranty from them (all is good now, im happy with it)
