<font color='#000080'>If you've got that sort of money to spend, why not an aqua-vision torch? They seem ok, and I've seena couple in action, halogen umbilicals. I think it's
www.aqua-vision.co.uk but I'm not sure.
Have you thought about Mark Chase's 2nd hand CD umbilical? Send him a PM, see if he's selling it. I think he said he was on the DIR forum.
Hope this helps.
