I will ring on this bell....
I have and want only one body which I intend to use for life...
It becomes such a personal thing which develops its own history. Your history, becoming more and more attractive as it does.
One could never sell it or part with it....it becomes an old friend.
I have absolutely no problem with scratches, wear, etc. Free of all of that nonsense.
That mentality one must break from otherwise one will NEVER grow in their personal work. I am further moving that direction with lenses as well. As long as it has fine optics, I don't give a d@mn if it has barrel wear.
However, the camera is non-negotiable.
Further, this is the last mechanical M. Do you realize the implications of that historically?
I purchased mine new/used 3 years ago for $1900 from a guy off of pnet.
I see them now selling easily online for $27-2900. With patience, a lot of patience perhaps, I am sure you may find one for sale again. The value will donothing but increase...if you are into that kind of thing.
Used or not, get it. It is far more refined than the M6 series. You will not regret it. you will love it, grow with it. It is a very personal machine that becomes part of you in time.
My goodness, to have the modern oprion of black paint over brass. There is no option here...Don't settle.
If to do over again, well, one apparently doesn't find many of these for sale.
I have recently seen a black paint M3 for sale on the auction site.
It was redone by a very famous Japanese fellow that specializes in stripping the chrome and baking black lacquer in the traditional manner.
It looked fantastic, and was selling for $1300 or so.
The Japanese as you know are obsessed with Leica. This fellow is world reknowned.
No it is not "original" if you wish to look up the serial numbers, but who on earth cares. It was genuinely beautiful, and very well done.
The M3 is arguably the best Leica ever made.
These are options I highly recommend fwiw. I do not know your level of experience, but you will not regret this, and will if you don't go this route in the future ( I feel this strongly about these aspects mentioned above).
Regardless, have fun and best of luck.
