AliExpress is by far the cheapest for the GTmedia, the UK warehouse had stock last week as well they said.
I set the folks up with them this weekend, one on a static dish and one on a motor and even though they get more channels they hate the usability so far. I think they're easy and the benefits outweigh the cons but certainly a factor to think about for any technophobes.
All mine are HW 1.0.1, one of the remotes has a narrower IR window than the other two though. Starsat with the WiFi remote is the best I've used on this type of box, shame they don't all use it.
The V8UHD has the code in there for the CHMax online channel stuff but so far any variant of the serial I've tried on the MM site doesn't recognise the serial of these.
Hopefully a sign of things to come.
