@dysfun I realise there is a joke about this.
But we have evaluated the idea of offshore manufacture, and, basically, for us, keeping production of literally everything where we can visit factories to supervise QC actually allows for a much higher quality end product.
Pick-and-place/reflow = Newbury
CNC machining of casework = High Wycombe
Final assembly = Wokingham
We literally pay visits to where these processes take place.
