What's better: Vacuum or Pressure bleeders?

Want to buy one of these so I can change my brake fluid by myself...

Adam,
Take a look at the MP website:

This little outfit works as good as my friend's $600 Snap-On vac brake bleeder.
You can't go wrong for $44. You can order direct, or from Pelican, too.

I have a vacuum tool, and it works on brakes, and it works for testing other stuff...brake booster diaphrams, vacuum advances, sucks up liquids....

But I suspect that the pressure bleeders are a little better for brake bleeding.

If you use the pressure type you will have to plug or crimp the vent hose on the resevoir closed to avoid pumping fluid out during pressure charging. I my opinion the pressure type is best. I've tried the suction type and they are less efficient since they suck air around the bleeder fittings threads during the bleeding process; it just takes longer to do the job with this type. An alternate that nobody has mentioned is replacing the bleeder fittings with the aftermarket fittings available that have a check valve built-in and thread sealer to elliminate leak-by; you just open the fitting and pump the brakes, that simple! Wonder if Pelican sells these, I saw them advertised in the Ecklers catalog (for Corvettes), the manufacturer makes them for most other popular applications as well.
