I purchased one of the Motive power bleeders several years ago and I have found it to be a useful thing, particularly when you need to bleed the brakes or clutch and no one is around to pump the pedals.  Just fill it up, pump up the pressure a bit (a gauge is built in with it) and bleed away.  I heartily endorse it!
