Tesco Outlet are selling off refurbished Dion 250 GB Freeview recorders at just under 30 quid including delivery and with a one year warranty.
I bought one for about 45 quid a year ago (from someone else on Ebay, not having seen Tesco selling them on Ebay, if they did) and can recommend the box as a cheap recorder. Tesco had new stock in store last Autumn/ Winter at over 75 quid, so this 30 pound price is something of a bargain in my view...
see cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=271033410955
Remember this is FREEVIEW not FREESAT (cheapest FreeSat recorder around 200 pounds)
