I need a pulley

I need a smaller Alternator pulley than stock. I have a 200 amp alternator and the turn on rpm is about 1150 rpm. so I need to spin it faster. I have thought about an overdrive pulley for the crank but I don't want to overdrive everything.

Does anybody have a suggestion or a link to a site as to where I can get one?

Why not just bump up your idle in the tune? And yocrew is right, the AEM pulley is the only actual underdrive pulley for the alternator. I did a quick froogle search, and this is the cheapest I could find.
