starter motor alternative

["Evangelos G. Makris" <emakris@hol.gr>]

My starter motor is beginning to go crazy once in a while
and I'm thinking of replacing it.

I can't remember where I saw an ad for a "new" starter motor
that draws less current, turns faster, higher torque, blah, blah...

Could anyone help? Is there such a thing available for
A-Series engines (12V prefix), negative ground, non-preengaged?
