Firstly, no snakes enjoy being handled by us pesky humans, nor are they sociable. They are solitary animals, and if they seem to enjoy us, it is becuase of different reasons such as our heat output, escape notions, etc. Some are simply more tolerant of being handled than others, but we must not anthromophize these animals to death and lose understanding of their behaviours. Second observation I made from your post was that you feed your snake every 3 weeks, less than your snake wants, becuase you want more time to handle him. Please correct me if I'm wrong, but that's how it came across. If your snake comes out of his hiding its most likely because he's looking for a meal, hence he should be fed, not handled for a week more. Typically snakes should be fed every 7-14 days, depending on the species and indivdual (excluding large python species such as burms, retics, etc).
For the most part, I've found more BCC to be very sensitive temperament-wise than not. I wouldn't consider them to be a laid back species. LOL... and none of my BCC even appear to enjoy being handled at all, in fact its quite the opposite with them
Some seem to mature into very laidback animals, but for the most part I would have to say they are a more sensitive species. BCI tend to be a lot more laidback, if handled as babies, but again, I've seen quite a few agressive BCI as well.
I don't live in the states, so I cannot recommend any breeders/brokers from personal experience. However, I have am familiar with the type of animals, and communicated with several breeders/brokers and private hobbyists that have been able to deal with them firsthand, so I can pass on what I have drawn from that. Not all are breeders, some are brokers, all produce/sell amazing looking animals, and hold great reputations
I'm sure someone will be able to add many more to the list, but these are the ones that I feel comfortable listing...

Also, two private hobbyists that occassionally offer some absolutely stunning animals for sale (I would jump on them in a second if I had the chance) post under the names CE, and petersboas, on that other site
