Bob!!
Come to Michigan!!  It's not only a pretty state, but this old dog and the great old dogs I worked with made excellent neutral buffered formalin---yes weighing out the buffers for MANY good years!!!!  With downsizing, we've been forced to purchase it now, but were successful for a long time making our own!!  Never say never, Bob!!!
