I don't sell h2h boxes but when I read the thread I did ask the person I deal with at Air digital, I was told they still have some stock of the H2H in their UK warehouse, although not many. Do I want to order some? I explained why I was asking and the response was
'ah.there is not many h2h on stock.maybe some customers want to change h2s to h2h.so we sell tuner to them.it is the same mainchipset with them then just change one tuner.it is easy.'
They haven't said that there will not be any new stock but that wouldn't surprise me, as the forum sponsor has said, there are other models that will replace it. ie H52tc or H4 etc
