I was gonna buy a digihome PVR80 (currently nearly £80.00 in argos) off them for £39.99 plus £8.00 delivery on ebay but decided to check thier website and got the same box for £39.99 free delivery (ordered Monday got it Wednesday) I presume they save on ebay fees.
It's a 80Gb (nearly 38 hours), twin tuner, Picture in Picture, Timeshift (pause live TV), 7day EPG but it won;t let you record 2 channels at once..but there is firmware on the internet that will allow you to do that at the expense of memory for the EPG... (firmware upgradable via serial cable)
They also do a 160Gb system for about £10 more..
I only bought it as the DVB change meant our ECHOSTAR was useless
