In reply to Indy:
Why not? What could be nicer than getting creative with a fine machine that is already manufactured and has been lovingly cared for by a rich amateur, now cheaper than you couldn't afford before? Perhaps only using one that a parent left behind for you - in answer to that.
There's a great rangefinder community online and in the physical world, as I am sure you've discovered. But there are plenty of other fine camera systems waiting to be bought and used again as well.
Perhaps processing in your kitchen and scanning would give you the most satisfaction. But if you are in a hurry, chromogenic b&w prints and scans, back in 2 days from Photoexpress in Hull (which you can later either darkroom print or IR hardware scan at home for the special ones) is also an option. Or colour done by Peak Imaging?
Since Galen Rowell made masterful pictures using 135, the equipment (scanners, film, lenses, cameras) has only improved. So the end-product quality is guaranteed, to that extent. The market for film products has 'consolidated' as well, and with things like Kickstarter and 3D Printing, who doubts that film will ever stop being made in this global world?
There are things you realise, or re-realise, using film, that you forget cannot be put into words. And like a lot of consumer experience, things have never been better.
As for the lack of 'instant' feedback in terms of exposure, capture, and quality, you might find that it is no longer as important as it seemed: you are probably a better, more confident photographer, and you might be more patient.
Do it; you won't look back, except in awe.
