Well,
I have 2 boxes -- 7100 and 221 S Ci and like both of them. I guess satellite order is prepared for Turkish market ( maybe it's Turkish company located in Germany or mayve software is written by Turks). I have couple other HD tuners as well but Vantage is basic one due to picture quality, SATA option available. And my motorized system is operated by Vantage due to stability and repeatability. So my opinion is different to yours. I guess you can complain in their site vantage-digital
