Have had one for a few months now
And it's superb, really pleased with it. Added extra LNBs to an existing Sky dish and installed it ourselves.
I let the TV (Panasonic Viera) upscale the SD stuff by leaving the Foxsat on 'Original' but to be honest there isn't a huge amount in it, the scaling is fairly good on the Foxsat considering it's working with such highly compressed signals.
Two notable omissions from your review; firstly comparing it to Freeview and Virgin cable services is somewhat misleading as a large part of the purpose of Freesat is to offer digital TV to those areas not covered by any other service. Where I live we can't receive Freeview or cable and likely won't be able to do so for quite some time, so it's either Freesat or further enrich Rupert Murdoch, and I know which I'd rather choose.
Secondly you failed to point out that the USB ports can be used to archive recordings to external storage media such as memory sticks and hard drives - a useful features albeit a slightly limited one as you can't record directly onto an external drive.
And the killer feature, after being used to Sky - when scrolling through the small EPG whilst watching a program, pressing information fetches info for the program you're looking at on the EPG, not the one you're currently watching!
