Some small drill presses for mini drills work OK, but you can build your  
own "pivoting drill press" far cheaper.

You should use a drill stand that has smooth, straight movement, and  
little play. In it you want a spindle/grinder/mini drill with high RPM (at  
least 10000), little play in the bearings and little runout. The best seem  
to have precision ground collets, the cheaper ones with aluminum or brass  
collets that "can be put in there" but don't really _fit_ might not work  
well.
Having that, you will not have any trouble with drilling.
