Guys, due to the Moravian delay in the production of the Enhanced Cooling versions of the G4 camera interest probably has suffered, I put off my own decision to purchase until all sorted out.
Camera is available and I attach a link to the UK pricing I've just received (heavily affected by impact on Exchange Rate due to recent EU Referrendum vote). N.B note the need to use the external filter wheel (50mm square filters).
