Qwiksilver carb for 300ex?

Is the qwiksilver pumper carb. available for the 300ex yet? If so, where can I get one? And how much should I expect to pay for it? Thanks for any replies.

They are listed in the catalog. Should be avilable. Just installed one on a 2000 400EX. Very nice...

The edelbrock catalogue? That shows one for the 300ex but I don't think it is a pumper carb. Also, can I just order directly from them? How much is it?
