I thought I would build a lift from available plans, but…
Here is a DIY computer controlled router lift that was a really satisfying project.
Made for a drop in router table and uses a stepper motor for precision movement.
Has an auto zero probe (that thing at the lower left in the first picture.)

Before you ask me why I bothered, take look at my blog here
which probably tells you more than you want to know. :^)
