The availability is definitely crazy for those who have been accompanying the hobby since its inception.
Going back to 1st October 1986 BCG Species List which is only limited to 17 species, tells us all how far it is has grown.
But to be honest, I am more amazed by how organized the hobby was back then, with newsletters, regular articles, all of those efforts which built the foundation in which we all of us are still standing on today. its just amazing if you think of all the limitations back then!
