My experience with my old R5 was that it was wonderful when it worked but no one would touch it when it went wrong except Leica and their estimate was for over 900 UK pounds.
OTOH you can get the R5 from time to time on ebay from dealers from about 65 to 120 pounds but the lenses are (very) dear. FWIW I've often been tempted but can't face the thought of regarding one as a disposable camera to be scrapped once something fails.
One other point, they are nice to handle but heavy and get heavier, somehow, as the day goes by...
Just my 2d worth.
