I have both a Mityvac vacuum unit and a Motive Products pressure bleeder. The pressure bleeder works better than the vacuum bleeder. My Mityvac sucks air around the brake valve no matter what I do so I always see air bubbles. The pressure bleeder pushes the fluid out so the only bubbles you see is the air in the brake line making it easy to tell when the line is free of air. In addition the pressure bleeder doesn't need a air source so you don't need power and an air hose. The purchase price of both units was very sim and you can even build your of pressure bleeder using a 1 gallon sprayer if your handy.
