I bought myself a very lightly used set of David Clark H10-60s, to replace my instructor's spare H10-30s during my PPL. Would've stuck with the -30s as I'm only doing fixed-wing but got a great deal on eBay. Having had first-hand experience of DCs, I was happy to continue knowing they would have good resale value or be a second headset when I upgrade to ANR in the future. But first I have to finish paying for a PPL and the cost for this set = 1 hour of training.
