Tim, Please note that just a short while ago, this issue sort of boiled over, which is why some people have trepidation in responding. It is not trying to avoid your question, nor to bad mouth other instructors, but someone tried to stir the pot and lots of questions regarding ethics, values and morals were raised, some in quite an ugly fashion.
In light of that, there are a lot of wounds which have just started to scab over, and picking at them, (in this group, it would be clearly unintentionally) is just not something people want to do.
The self certifying route is regarded by many as the least headache because it gives you only two "Masters" to serve, that is the BCA and the customer as far as who you are responsible.
Now, I am very sure that if you decided to self certify, and you came back and PM'd several of the instructors here about sitting in on one of their classes to give you something to compare your class with established classes, you would have no trouble gaining entrance. For the most part, this is a very helpful and very supportive group of people, and they are not going to leave you out in the cold, but they want the whole system to work.
