Nobody mentioning the Qbox Mini HD which is same price as TM800, plus around £35 for 2nd tuner and you've got twin tuner fully functional and runs off of Micro-SD cards
And much better software management on the box. No big wrong version library files or folders full of drivers for impossible PCI cards. Nicely written shell scripts. Only drawback is no internal disk, only usb disk recording. But my usb powered Buffalo disk works fine.
