Today there are many choices and Leica is just one of them. I love Leica glass more than Leica bodies (rangefinder) but the cost for both, more often than not, out weighed the results I achieved with the Leica gear.
I found myself missing shots as well and that, more than anything, was the reason I finally abandoned the M8. I sometimes miss it but those times are few and far between.
As has often been said... Leica is not for everybody.
