I used one for my M5 a while back (the OEM ER case for the M5 seemed impossible to find at a reasonable price), and I have used the ER cases made by Leitz for the M3. The quality is comparable, although the Kameraleder cases are probably marginally the better product. They're also substantially more modern-looking; it emanates a different affect. I found my Kameraleder case to be slightly more rigid than my M3 cases, but (a) I didn't have the Kameraleder case long enough for it to be broken in in any real sense, and (b) the M3 cases were over 40 years old and were quite well broken in.
They're pricey, to be sure -- but (a) as lots of Leica owners know, you never regret buying quality, and (b) if it's for a special camera that you'll anticipate keeping for a while, it's likely worth it. Of course, while I got rid of that old M5 in a paroxysm of gear-shedding (together with the case), I don't particularly pine over the case -- though I do so over the M5.
