Good value mobile sellers in Central London?

Archived from groups: alt.cellular.nokia (More info?)

Can anyone recommend a place in central London that sells mobile accessories
(esp. Bluetooth) of good quality at a reasonable price. Have noticed that
much of the stuff at Carphone warehouse, the Link and other chains can be
had for cheaper elsewhere. I'd buy from an online shop, but wanted to get
hold of a headset quickly as am going away and don't want to take my chances
on an unknown in Tottenham Court Road, where if there are any problems with
quality or compatibility, they're unlikely to give me the time of day once
they've got my money.

Suggestions welcome!
