Mine broke :-( so I need a new one, I think it's the CST-75.
Anyway the best price I can find so far is £14.99 on the http://www.se-store.co.uk/
SonyEricsson store .
I'd also quite like a car charger, the CLA-60 I believe is compatible with the k800i and again the only place I've found it is the http://www.se-store.co.uk/
SonyEricsson store where it's £15.99.
I'm only after the official Sony Ericsson stuff, I've had bad experiences in the past with third party stuff so don't risk it anymore.
Anyone know of any better prices than those or recommend some good websites for mobile accessories? I really don't have a clue where to look.
