I have spent the past year dealing with a bad case of SBAD. While my 18 brushes are only 10% of DrP's collection, each was carefully chosen and I have learned a lot about what I like in a shaving brush. I find brushes to be one of the most fun aspects of our hobby because there are so many different options and each one is different from the next making it a unique work of art. The main problem with a collection this size is that if you rotate through them then each one only comes up for use a couple of times a month. On the plus side, none of them will be worn out from overuse and so they should more than last for my remaining years on this planet!
