Thanks Troy and Brent.
yes I have had a play around with the EX 430,it really is amazing,and quite capable of a lot more than I expected.It also has a great FOI (fun on investment) factor!!
I really like how the head tilts around in all different directions,this allow great use of ceilings and roof.I will have a look at Dennis's Lumiquest box Troy when he comes up,David has offered me his Bracket and some other gear to play around with,before I go making any major purchases Troy,so don't worry I will not be purchasing any major items in a big hurry.
But it does appear you are right,that for most of my applications the ex 430 seting on top will do very nicely,if there is no wall or ceiling I have some off cuts of jip-rock that will suffice,by some holding them.Lighting does appear one area,where the handy amatuer photographer can save some money.(for once!)
Ok,thanks all for your help and links
