If you're willing to learn a little about firmware updating and TAPS, it would be worth searching local Currys/PC World for the Topfield 5800 PVRs which they've recently discontinued - priced at £79.97 (the 5810 which includes an HDMI output but no RF modulator isn't yet reduced, and is also not recommended due to buggy standard firmware and heat/ventilation concerns).
The TF5800PVRt (facelift) has a 250GB HDD and Freeview+ firmware, although downgrading it and installing "Mystuff 6.2" makes it a superb machine. Easy transfer of recordings from (and to) it with a PC.
