[Leica] It is worth to sell an old Leica to by a new one??

[Francesc Castells <fcpique@tinet.org>]

Hello leica-users members,

I'm new as leica-user  member, and I want to start asking very simple
questions to the group
1/
I have an M3 working properly, with Summicron 5cm 1:2 and  Elmar 9cm 1:4. Do
you thing it is worth to sell them to by a new R??
Do you have any idea of the price of this M3 set in the occasion market?

2/
I have also a Leica-meter MC, installed over the mentioned M3, that does not
give any signal to the light. Do you know if it is possible to repair  and
where?

Thank you for your help

Francesc
