Thanks Jenseneverest, that's good news re the H7s - I think I'll wait although this box looks really good too. What a massive improvement on the cloudbox they started off with all those years ago :-)
Thanks for clarifying re the tuner setup, it was the specs from Airsat that I found confusing; I guess internally one tuner is Sat only and the second internal tuner is a combo (albeit with s2x for multi stream) and that both parts of the combo tuner can be used at the same time? If only I'd watched the video you posted before I'd asked it would have made sense...my bad ;-)
Looks like for motorised users having S2X is the way forward ;-)
