Depends on the area you live in. If you go here you can enter your postcode and see whats available.

In the Glasgow area there is a huge range - all the BBC stations and local stations are on DAB as well many national stations usually found an MW. Many stations are unique to DAB.

The quality is good enough I suppose, but I've yet to find one above 128kbps. Stations usually on MW sound a LOT better, but sometimes I find that FM is clearer. Thats another thing - DAB is only good if you get a clear signal. If you get a weak signal you totally lose the station - this doesn't happen with FM so its good that many radios have the FM tuner as well.

Some cool things are scrolling text for station info and lyrics etc. Well woth the £99 I paid 2 years back.
