I can't speak for the quality of their AV products, but MCM has such
components. And you can get a reseller certificate for a lower price.
(You'll have to show MCM you have a business license.)

There's another absolutely terrific company whose name I forget. (Two words,
both starting with S. I think.) But their people are absolutely grand.
Customer satisfaction is not only their #1 priority, but seemingly their
only priority.
