I have one of these, great piece of kit.
Firstly I would recommend open vix image, with blud HD skin (Sky HD) easy to do, just google for info as I did (normally diverts you to here anyhow lol)
Hardware wise seems very solid equipment, remote control is good too.
Never let me down so far, had it 18 months.
Might be a little time consuming setting up but so much better than the F5's of this world.
