Get yourself a Vu Duo 2 with Vix operating system. Get yourself a satellite line for £45 a year. Full Sky Package, + BT sport + Box office events + Adult if that's your thing. Has IPTV built in plus Kodi.
Importantly it all looks and feels like sky when you put the correct skin on. I hate the Kodi interface so don't use it but with the satellite line you don't really need it.
Plus all the Showbox stuff is all on demand through your remote........allegedly
