To be more specific:
I tried a hand actuated Mighty Vac, and it was too slow for efficient bleeding, and does not stand upright on its own. At least on the one I had, the reservoir was too small to do a whole system flush, and I overfilled it once by mistake. Once it got brake fluid in the mechanism, it never operated properly again.
Perhaps they have other models, but I gave up on them.
It was this 'SilverLine' model (like $80-90):

Now looking around, I see they are also marketing a big vacuum transfer pump with the Mighty-Vac label on it. You will see this same unit with like 50 other brand names on it.
I have one that was packaged as an oil extractor (same, but no bleeder fittings). I have the manual one (not the pneumatic).
It sucked oil pretty well, but a 2-foot drop (empty, in its box) shattered the base, and split the container open. I was the clutz, but that seemed pretty weak to me. Never tried it for brakes because I have the Vacula. But hey, the pneumatic one has a different base under the container. Certainly cheaper than the Vacula, holds 6.5 liters, and can be used for other purposes.
