10GB ethernet switches will never be cheap because of the power requirements. Just get a 25GB switch and skip 10GB all together.

Of course they will go down in power just like these USB controllers have done.

25GB switches do 1/10/25GB, can be used with copper and fiber, use a magnitude less in power per port than a 10GB copper switch and cost the same or less per port than existing 10GB copper switchs.
