The basic Digihome T810 is very reliable,
in my experience (just wish it had stronger tuners, it will be OK as long as you have good reception/good aerial). Just make sure you are getting the model number
PVR80 or
PVR160,
not a DTR+++.
In the thread about converting the T810 to a twin-record, you'll find other model names that are clones, eg, Goodmans and some sold by Tesco/Asda etc.
If you're buying online and the picture has the Freeview Playback logo, then it'll be a T816 or T825, the buggy ones. Only trouble is, some eBay sellers are passing off the T810 as Freeview Playback... it's a minefield out there
