Budget and Leica don't seem to go together. I'm not sure if/why it takes more labor to lube than a Pentax, but it costs 3-times the price.
I had a local guy who did camera repairs once show me two parts that did the same thing in a Nikon camera -- one part, fairly complex, fit in the cheaper camera while the same part (or same function, anyway), fairly simple in construction, fit in a more expensive camera.
The simpler part cost more. Why? They figure if you own the expensive camera, you can pay more. Last time I discussed repairs with the pros at the local paper where I worked, they complained that any service, for anything, on their spiffy new $5 K digital canons, cost around $700.:confused:
Same deal.
Leicas are wonderful cameras and we want them to work. If paying a few skilled craftspeople whatever they want to fix them is what it takes, I'm happy to pay.
