This is what I use.  With the right lighting, you can do some pretty
accurate manual drilling, even with crappy, aging eyes like mine.  For
a row of holes (header, dip, sip, ...), align one end in x and y, lock
one of the axes and then step down the row, drilling.  Works pretty
good and fast.  I get good enough alignment to smoothly slip the part
in, even a dip or multi-row header.

I've given thought to CNCing my cross sliding vice ($45, from
grizzley) but it has a lot of backlash and 4 TPI leads so the accuracy
wont be too high.  Worth looking into antibacklash mods.  Still, it
would be a bit of a franken-tool.  

The best solution is to SMD as much as you can.  Anyone seen decent
SMD headers?
