Thanks guys, just pulled the trigger on the fc 710 and a glass female to female adapter... Altogether cost £28 shipped to the UK, which is ridiculously cheap (I guess that's how they get us hooked with chronic GAS).
The reviews of the fc 710 sound like exactly what I'm after, and I saw an awesome slo mo vid of it in action, so thanks
@Frederick McGuire for pointing me in the right direction.
Now I wonder what's going to turn up first, my glass from China, or my Grasshopper from never never land .
Peace, il let u know what I think!
