If I had the money I'd seriously consider it. I like old Leicas and I'm a sucker for the Leicavit. But I don't have that sort of money. Unless you do, why worry? And why tut-tut about it and construct pointless fantasies?
It's like saying Rollers and Ferraris 'aren't worth it.' I've had friends who differ -- but they had the money, and I don't. I'm not really qualified to judge, except at second hand thanks to the kindness of those friends; and I suspect that most of those who suck their teeth about all the above -- Leicas, Rolls-Royces, Bristols, or to switch to motorcycles, Brough Superiors or Heskeths, both of which I have ridden and would buy if I could afford them -- either have no experience of any of them OR far more likely could never afford one.
Cheers,
Roger
