Dual belt Alt pulley?

[Version6]

I looked through here for sources of a Dual belt alt pulley in the stock diameter and only was able to find the Banzai Racing one, but they only sell it in a Kit with two belts.

I tend to have bad luck with belts so I often stock up on a couple of extras and I'm currently at 3 spares. I don't need 2 extra belts but they won't sell the pulley by itself (already asked).

Are there any other companies that offer a dual alt belt pulley in the stock diameter?

Try RESPEED, they sell a stock diameter dual pulley w/o the belts.

RESPEED seems like the best bet for me, though the aluminum one from Atkins makes me drool a little.
