[Leica] SD Card for M Mono Type 1

[Lew Schwartz]

I can't get my MM1 started with the same card I stored it away with and
l-forum is telling me that good cards are brand and spec specific. I am
asking for the brand & spec of cards that the lug has used & feel are 100%
reliable.
Here's what I've cobbled together on the spec so far. I doubt if anyone is
making these any more.

SDHC UHS I 16gb speed <30MB/s (yes, less than).
