I really cannot understand why folk pay so much for flying kit. My headsets cost £25 and £48 on Ebay, standard DC products that cost megabucks from Transair. My flight bag came from the market at £2.99 and my stopwatch from a mail-order tool shop at £3.99.
And I have a whizzywheel somewhere that is free to any caller, I never used it after I got my license. Still can't believe we are expected to use such ancient kit in the 21st century!
