I use a manual impact driver from Sears. The bit for the flat blade is large and wide and fits into the lower unit plugs very well. You turn the handle as if you were going to unscrew and hold it at the stop, then a quick whack with the hammer twists the tool and has always popped even the worst plugs free for me. Plus it's pretty short money ($25), considering you can also use it on bolts with 1/2" drive sockets, 3/8" with the proper adapter. Check it out:
