I have not checked their prices.
I built a CB plug and mold combo over the winter, it's on my site.
I vacuum bag with carbon and glass.
I popped out two parts a few weeks ago and then glued them up,
and I looks good. I was not pleased with the stiffness so I will add a few more layers of carbon on the next one.

Here I a shot of the plug.
