My advice would be to increase your husbandry skills. BRBs require alot more accurate temp and humidity than balls or BCIs so that makes them more of an intermediate level snake. There is a care sheet on NERDs site that is great: http://www.newenglandreptile.com/CareBRB.html

BRBs are on my 'to get' list (ha ha...just like everything else). My wife really likes them. They are awesome beautiful animals. I almost considered purchasing one a while back but decided to fine tune my husbandry skills with my ball pythons (since they are a bit more forgiving) before getting a BRB. As far a breeders, I have seen a few breeders that breed them 'on and off' and some that aren't really producing normals right now due to morph projects.

Good luck and prepare very well
