A long winded and semi humorous (?) response.
Xtrend …. Quality, innovative(ET8500 - loved by few but my favourite box) and overall excellent receivers - in my view hard to beat during their unfortunately short lifetime.
Vu+ - I swore I would never have one of these overpriced boxes(my view), but acquired one 6 months ago(uno4kSE) to help get Vu multiboot running - and I have to say nice quality box.
Gigablue …. I have 3 of these quality boxes(my view) …gbuhd4k, my main (lounge) box, gbue4k(test, so gets beaten to death) and a gbtrio4k which is my sf8008 tester, so I can test instead of using the sf8008 ( see below). My only question for gigablue as a ET10000 replacement is whether you can get the T2 tuners if needed.
Zgemma, low priced, does what it says on the tin( a bit like the receiver casing).Unfortunately uses their home baked servicehilicon component instead of servicemp3.
Octagon sf8008 - well after much fine tuning, this box does a good job, although it pains me to say so. As the only box that I have ever managed to mess up, its now consigned to the dustbin.
So if you need T2 then maybe Vu+, otherwise gbue4k or gbtrio4k(and Yes if you really want to sf8008!)
Not sure about the Ziggo CI card, but CI+ works on these boxes. As does most IPTV. Lcd screen, you can power off, turn to black.
