I have just bought a Sagem DVR 6200T for £29.35 (after VAT reduction) from my local Sainsburys (Leamington Spa).
OK, it's not the best DVR in the world but it's an excellent price for a twin Freeview tuner with a 160Gb hard drive!. You could pay that much for the hard disk alone!
The model number on the side of the box is:-
