Yes, I was going to suggest the USCCA. A friend of mine (also an NRA certified instructor) took their certification course and he thinks it's excellent material.
I have some reservations about them, because they are basically a sales arm for the insurance company they are "affiliated:" with, but it may be that they will become the de facto standard for training. It doesn't help me -- my state stipulates the NRA Basic Pistol class as the prerequisite for a carry permit, so I'll maintain my NRA cert as long as it's available. If the NRA ever goes belly up, we'll have to approach the State Police and see if we can continue offering the same course even if the NRA no longer exists.
I'm still hoping that the NY court will boot LaPierre and the current board of directors, and give the organization back to the members. (I know ... dream on.)
