Wanted this myself. Kicking myself I bought a MS Wireless 3000 2 days back.
Good set. Good 4/5 star reviews all around.
Found in Canterbury high street Currys but good stock around Canterbury (inc the 'new' combined Currys/PCWorld and around Norwich - my home - so I would imagine good stock all around even if it is a clearance price).
