There are no Freesats made by Humax anymore, someone pointed me to Amazon.de where there were several for sale but I am pretty sure they are not Freesat but perhaps whatever the German equivalent is.
Freesat’s own site features Manhattan and another that I do not know the name of but, they all come from the UK which is a nono for us now. On their site directed at French users they link to a Paris firm that markets these at € 515 each including delivery. 
I have no need of new Manhattans, I already have 2 which work perfectly well apart from not recording.
I have no need of HD either. Try as I might I cannot see any difference between HD and SD, maybe it is my eyes or my brain, but they both seem identical to me.
Having got the Humax to work now, because it has features which I do not like, no ITV, a foreshortened EPG list and a rather longwinded reminder system, I have disconnected it and am now back on Manhattan till next Saturday night, when I need it to record early morning serials. After that it will stay connected for a day or so just long enough for me to see the replays, and then ‘back in the box’ for another week. 
Another success is that I managed to get back my French Fransat connection after visiting workmen broke the LNB bracket. Easy to retune with my wife in the room on the phone to me outside and a roll of duck tape to shore up the bracket.
Thank goodness they aren’t on the roof.
