why no boosters?

[absintheisfun]

My knowledge of brakes is...well...none.

In planning out my car, I was leaning towards wilwood, but after looking at several builds on this site and others, I noticed that many people chose not to go with a brake booster.

Does the absense of a booster imply that there are no power brakes? If so, why would you do this?

There is a master cylinder that I've seen advertized somewhere (i don't remember the name or place) that is an electric booster/master cylinder/proportioning valve all in one. It looks pretty slick, but it is not very cheap.

Another alternative is the hydtroboost system from CPP.

But ultimately, I'm just curious why so many people go without the booster (other than the fact that its big and ugly...)
