Having owned one (with a diabalo 2.3) for a while, technically I see nothing wrong with them.
If your a feed hunter they have a reasonable blind scan, and with the right patch / soft cam keys 1degWest (Thor) is open without any other hardware.
Also they have HD out, and in theory unless the UK changes its mind again it will be a good FreeviewHD receiver (if we ever get it!)
Yes it does have an ethernet connection, but as far as I am aware all this is for is connecting to an "offical firmware server" and as a CLIENT for cardsharing - nothing else (eg remote streaming to your PC or editing settings via a webbrowser)
Heres the points to consider:
Even with an official card, it can't decode anything Nagravision 3 (which may be a major issue should anyone figure out how to get around it - to the point where a new reciver may be required if a cam cannot get round the limitation)
With the recent change of several high profile channels (eg Premier) going to Nagra 3 and those on Nagra 2 likely to change its days are numbered hardware wise.
[im 99% sure thats true - please correct me if i'm wrong on this point]
Also with all the card changes that seem to be happening, it may be better to wait and see what remains in the near / medium feature to see if the box becomes obsolete before its time
bottom line, good piece of HD kit that may very soon be obsolete for all bar FTA
all above IMHO - don't flame me if you disagree, but please correct any inaccuracies - many thanks
