High Amp alternator

Anyone try the tuff stuff high amp alternators?(sorry if this has been discussed before) 100 Amp to be exact internal or external regulator? I was gonna go with a (cough cough) GM CS type but:thebirdm: I'd rather stick with whats right, besides those cs's are ugly, if not tuff stuff what will work? SB, mech w/p and f/p,single electric fan, underdrive pulleys(march performance ratio), MPP electronic ignition with promaster coil and summit box with rev limiter, no power steering or A/C,thanx.
