Good Car Audio Stockist in North East

[Davo456gt]

after some hands on advice, and want to be able to see some flip out 7" single din car audio units with rear camera ability (thinking Alpine, Kenwood, Pionner, Clarion perhaps)

Where would you recommend I go in the North east to see and talk to someone?

Halfords - well they do stock Pioneer
PDACar in Harrogate ? how much do they have in stock ?
place under the B&Q bridge in Newcastle - can't remember what its called now, but was told they are expensive ?
Carsound in Middlesbrough - think they have ceased trading ?

Any recommendations, much appreciated please
