I've owned one of these since Xmas 2007, and it is amazing value for money at the reduced price. It's compatible with Twonky Media, so I can access my music via a home network server. It will also work with the Squeezecentre Music Server, although less well than Twonky. The Firefly media server freely available from Roku works okay as well.

In terms of sound reproduction, this device is fantanstic.

The internet radio section is, however, not up to scratch if you want to listen to radios 1, 2, 3 or 4. For some reason the radio won't connect to these stations at all. I even tried to access then via Squeezecentre and RadioTime, but this didn't work either.

If you want to listen to BBC stations via the internet (as I do), then buy an internet radio with Reciva software onboard - e.g. Roberts or Acoustic Energy products. These provide many more stations than Roku.
