93 Master cylinder

Okay hers the deal I have a 93 integra ls that seems like its master cylinder(brakes duh...) is goung bad. The pedal every now and then will go to the floor. I know that replacing this is extremely easy but was wondering, are there any other master cylinders that will fit on that brake booster, and will push more fluid, maybe a prelude??? Not sure someone help, also who make good aftermarket masters???:thefinger
