like MattKing,
none of my medium format cameras have a built in light meter.

none of my large format cameras have one either.

I have never used a spot meter and I don't see any reason what-so-ever that I ever would.

I too make frequent use of a simple handheld incident light meter

and sometimes, I even use gut feel to set the exposure - it is easier than you might think!

You certainly DO NOT NEED a spot meter!
