"Visiting a TANDY Store", Sorry to tell you that Tandy stopped trading in the UK around 3 or 4 years ago and sold their shops to Carphone Warehouse. You could try MAPLIN's, CURRY's, DIXONS, POUNDSTRETCHER's etc all nationwide chains. You could also try the first street market you come across. They will sell you the same gear with a different lable but cheeper. Expect to pay £3 to £5.
