I'm not aware any zgemma twin tuner cable boxes, yet! Solo2 is twin sat but can run the vu turbo cable usb tuner ( I have one ) but only one tuner still for cable, I have found the xtrend et8000 with twin cable and single sat tuner to the best value option, internal hdd too and very speedy. I also have the et10000 with 2 of each tuners but I find the sat tuners get very little usage so triple tuner et8000 was/is good enough for me although would love a vu 4k box, although pointless at the moment as we don't even get hd on sly.....would like a duo2 aswell lol
