We don't sell external licenses, so by saying this I am not competing or conflicting with NDC's offer here:
Before we got our own Cpanel Partner NOC license, we got all of our license through NDC. These guys know how to run a business. Excellent pricing and, more importantly, GREAT customer service. We had switched to them after having a horrible experience with another CPanel dealer and I just can't say enough good things about NDC. I believe, at the time we ended up moving our licenses to our own account, we had about 25 Cpanel licenses with NDC and I was actually a bit sorry to leave them.
