I considered the same set, though someone local was selling some David Clarks 10-13.4. I've since bought a pair of the Flightcom 4DLX (not sure if they're foreign as they're called 4DLX Blackhawk) for passengers. Many people say there is no difference, though in my opinion the DC's are so superior there is no comparison. You should be able to get some on Ebay for £100-120.
