I was thinking of getting a Proxxon Micromot MB 140/S drillstand for it, unless I find a regular drill press cheaper. Even then, a cheap drillstand might be a gamble as to how well it drills PCB material.
You don't want it to wobble from side to side at all. You may
consider doing the following:
1) elevate the board on a platform with a 1/4 inch hole in it.
2) light the board from above
3) have an optical crosshair and eyepiece focused on the bottom of the
board. I'd suggest using a 45 degree mirror.
4) have some sort of dust collector on the top
5) use a BB gun sight with the little red dot for the bottom sight
alignment if it works. The dot can be adjusted to match the exact
location of the hole you'll drill.
This way, you position the board over the cross hairs, then just
drill. If you ever have to align top and bottom boards, this makes
the alignment easy when you do the patterns first and glue the boards
together.
