Glad I missed out on the supposedly buggy Grundig Freesat recorder deal the other day now. The HDFS is very well reviewed as a quality HD receiver which can record to any USB Drive. In the small world of Freesat boxes is generally considered second only to the Humax HDR which was a scorching deal a couple of days back at just under £200, this is £44.
Clearly the capacity will depend on the USB drive added, it is also only single tuner. The picture quality is top notch, the box is stable and the thing is German made with a three year warranty. Looks nice to boot :-)

First time I have found a bargain in Tesco personally so can finally say they do exist.
