Looks like the same item is far cheaper on e-bay (?8.97 free P&P)- but does not have good reviews -

I was underground with a film crew yesterday at Cwmystwyth and my 'guest' had something similar mounted on a long arm off his helmet so he could see the screen as he filmed.

They had a selection of different cameras, I asked how much their biggest and best was and was told ?22,000
