USB versions are handy if you have a laptop as you can take it away with you. The Elgato Netstream DTT looks pretty good if you want to keep things tidy and have more than one computer to watch TV on.
 
I think the Netstream just sends the signal to your computers and you install the eyeTV software on them, eyeTV handles all the recording and gets the program schedules from tvtv.
 
Not that o should have to jstify myself but I am moving and won't have sky for a while so thought I'd take advantage of my spare hard drive bay and plonk a spare 1tb drive I have in there!
