For my R6 I paid "top dollar" and bought it from Leica Classic, with 12 months warranty. If there is an issue with the camera, I will take it back to them and have it sorted.
Life is too short to fiddle with toys which should bring pleasure. Unless fiddling with toys brings you pleasure. You can see that sometimes in photo forums. People are fiddling with this folder and that box camera and this Cosina or Praktiker 1970s SLR, fretting about changing this and repairing that.
FWIW Leica Classic has a good handful of R bodies on their website, in case anyone is interested, including several R4 and R5 that cost less than Apple earplugs that most people consider being "Disposable". Just buy a body, a nice lens and off you go!
As an afterthought:
When reading discussions on photo forums, I'm always struck by the contrast in how people talk about spending money. On the one hand, it's perfectly normal to see photographers casually debating whether a new M-mount lens with APO or updated coatings is worth dropping four figures—often to replace something only marginally “worse.”
But shift the conversation to R-series cameras and lenses—often optically identical to their M counterparts from the same era—and suddenly a few hundred euros are considered “expensive” or not worth it.
It’s curious how perceived value shifts so drastically based on mount and hype, even when the glass is essentially the same.
