i can highly recommend elgato's gear
i replaced my sony hdr860x that cost £500 and was as noisy as a vacuum cleaner with a £90 dvb-t elgato usb-2 add on that is silent , very reliable and produces a stunning picture
the eyetv v2.0 epg has to be seen to be enjoyed too ,wipes the floor with anything else i've seen for sheer user friendliness
i particularly love the way you can search via the text box for programmes , say heston brings up charlton heston and heston blumenthal etc etc
