The cost in 2006 was about £150ish and I was unable to ascertain a more up to date price, however, the UK suppliers of this German product offer a rental service (£30 per pair for first two weeks with £9 per additional consecutive week; full hire cost deducted from purchase price when you eventually buy) which sounds like a fair deal. they seem very helpful and knowledgeable. P&P is on top. check out the link and request a brochure . . . jesi
