Lots of good ways in this thread. Here is one I just finished.

It uses half of the existing handle for everything:
1) pump handle
2) moving handle
3) release for lowering

The handle removes quickly to lay on top of the table for storage.

You only need to buy one part for about $3.
The only real work to do is to slightly enlarge the ID of the steel pipe to 5/8" so the pin will press in (well...hammer in).
The 5/8" dia. pin can be cut from the pump foot pedal, or it can a trailer hitch cross pin cut off. I had a trailer hitch adapter with a cross pin that was perfect.

Since my original modification here are two other mods I've done:

1) Added a bend to the handle using a 45 pipe elbow and two 1/2" pipe nipples
2) Added a plywood swivel top (pivot on a 1/4" bolt in center of table) to allow wider contact with the cabinet sides of older EM's
It pivots to make the table narrow enough to roll under the pinball game, then swivel the top while under the game.
