Maybe this one? it sounds good.
Two problems I can see from the git-go with that Micro-Mark saw is the stroke length and the inability to use broken sawblades. You can see in the video that only about half an inch of the blade is being used. It won't last long that way and that section of the blade will dull or break. I don't see any way to narrow the blade holder to accept shorter, broken blades such as the standard jeweler's saw frame allows.
PS: Plus, a third observation... Being you will be changing broken blades often, I bet getting the bottom end clamped in and tightened would be a chore in itself. You could have a standard jeweler's saw frame re-adjusted, the blade mounted, and back to sawing before you could get out the tools to change a blade on the Micro-Mark.
Just my two cents worth.
