Just for information - this http://www.fotofixuk.co.uk/leicam.html
is an example of a company which is selling second-hand cameras, including Leicas, on the web and through its presentation inspires a little more confidence in me, cynical old bastard that I am, than you-know-who.
A very little confidence IMHO. Half their website doesn't work and they can't even be bothered to put up dummy pages such as under construction etc. Looks to me like someone working out of their garage. BTW do you have some connection with these people?
