Thanks all very much for your replies. On the point about live view - when shooting directly up in the air like I often do and close to the ground without lying under the camera its pretty much imposible to see at all - so in my case it doesn't help - actually I'd love to use live view - just waiting for someone to implement a live view feed to my ipad - that would solve all my problems !!!
Anyway for now I'm going ahead with the DR-5 and see how I get on - thanks again
