I use a Sekonic 188 which I got from Ebay for ~$25. Since I only need EV100,
I put a piece of Scotch Magic Tape on the panel and marked it with EV100. I
only need to press the button once to get EV100 then convert it by myself
for different ASA. Never bother to rotate the wheel or look for reading lock
. Couldn't be happier.
