I understand, Mark. I very nearly hit the go-no-further wall with my CLE but advice from this forum got it moving again. The Hexar gives a much better impression of solidity, and I understand they are still serviceable, but like any electronic device that has limits. And there are no shortage of them - and for the price of a ZM you could buy two. Or buy a replacement for not much more than the price of a quality CLA on a Leica.
I could give the standard RFF advice - you won't lose (much) money on buying and selling so you could buy, try, and sell what you don't use. But I'm useless at selling stuff so that advice doesn't work for me!
