My Humax's hard drive died and after reading the Computer Shopper '07 PVR review I decided to replace it with the Thompson as it seemed to do everything my Hummy did but is considerably cheaper. I found this price from Tesco Direct which is £10 cheaper than Argos who are out of stock. The cheapest Hummy is £140 direct from Humax.
The TopupTV pack which it comes with can fetch up to £30 on ebay too.
I just popped into Asda and they were £89.99 in there.
