JC Whitney and other discount auto places will sell you a little electric pump that does this same thing. Some you connect to a drill motor, some have alligator clips for 6 or 12 volts, some plug into the wall.
They'll suck all your oil out in a few seconds. Of course, to do a complete job of it you need to drain the sump too; I'm on soon for an SRM alloy sump with a drain plug like on my A65, keeps you from having to break that gasket seal every time you change oil; much less leaky.
Of course, if you get a certain amount of satisfaction from "make do and mend" solutions, salvaging a hand-pump from an old squirt bottle can be a way to go too.
