I picked up the original Leica case for the M3 with eyes attached. It is a much heavier made case than the standard one. It ran under $15 with priority shipping off of EBay. If I get ambitious, I will make the front section detachable. I picked up a standard Leica M3 leather case for $2 at a camera show. It does its job: protects the camera well. It is a better case than most new ones, and again should have used a detachable front. Nothing that can't be modified.
Not as pretty; not new; but cheap and serviceable.
