That's one of the many things I love about this site - post a question, and get several answers in a few minutes!
Have gone for the DR8 in the end, mainly for the switchable 30W/14W feature. £129 from Go-Dive.
Have also splashed out on a pony set-up (and not before time, yes, I know

).
Now just the VISA card to worry about

.
Surely now I must have all the kit I need and can stop blowing every last penny.... oh, except for the semi-dry and selection of clips I need to get at the weekend - arrrgh!
Cheers for the advice all,
Dave.
