I'm looking for some recommendations as to where to get a Sony TCD-D8 DAT 'Walkman' repaired - specifically in the London area (ideally SE).

In the past I've used Sony's Repair Centre @ Heathrow, but they no longer support repairs to their DAT range.

Last year I used a company listed on Sony's website as a recommended "local repair agent", based in Essex (mentioning no names), who took 7 months to repair one of our DATs - which was utterly frustrating.
