The one I got from Newark was about £35 4 or 5 years back, still works - I was going to say the whole point of these masks is not to have to do the 'nodding donkey' bit, but Rabs beat me to it! the difference between the £25 and the £120 one is approximately £95 ........ the only mask I've had fail was one of the £120+ ones (Speedglass) which did have the nicest styling but got the least testing as it fritzed irreparably.....
