I'd like a Leica, but as has been said already, it will be usurped by something else before long, so, on that basis, I think I'd rather get a M6 or 7 instead. Hell, maybe even one of the older classic ones!
I need money for this plan, yes, I know. I also want to start using my old Blad again, but the body is well and truly knackered (a 1967, 500N), so I think I'd need a new one. Yet more thousands.....
