The Kaon KVR-1000PLUS is reviewed in the Dec 2004 issue of Digital Satellite Choice. The Kaon HSC-N550H2R is reviewed in the 12-01/2005 issue of Tele Satellite International. Both look interesting (both can record up to 6 channels simultaneously, both have PC connectivity via USB 2.0, the KVR-1000PLUS also has an ethernet port), but I don't know if either is available in the UK.
Both have 80GB HDDs, which might soon feel a bit small if you can record that many channels at the same time.
