B7 2.0 vacuum pump oil leak-which manufacturer?

[wesalexleft]

Looks like the vacuum pump on the back of my 2.0 motor is leaking quite a bit of oil. It's run down the back of the engine, and onto the transmission. I've looked at some threads here, and most people had no luck replacing the pump gasket or seal to stop the oil leak, but instead needed to replace the entire vacuum pump with a newer revision model that relocates the o-ring. I know there are a few versions available, with ECS offering the "H" revision, but wondered what everyone recommended. The pump isn't cheap and ranges from 249.95, 265.45, and 337.78 by makers Pierburg, Vaico, and Audi respectively. Any opinions?

Pierburg makes our oem Diverter Valve I know that for sure, not sure though what brand is the vacuum pump, but I guess you can't go wrong with the Pierburg brand if you can find one.
