..because I finally got a drill press:
Rotwerk RB13Now I'm able to drill perfectly straight holes and will not have to deal with false ones.
Costs not so much as expected - in Germany it's sold around 147Euro (195$). That's the bottom range of money one can spend for reasonable drill press here.
I got it from Hornbach, a big semi-professional home improvement store here in Germany.
The Drill press is a sweet little one. Operating wonderful precise, really quite(!) and so much better.
Haven't done much with this one yet, but I guess it's a good one so far and worth a recommendation as a European 220V machine.
