I am an Earth Scientist working for a mining company, and find this program quite useful. Prior versions of EasyFit lacked several advanced models which I usually use, but this new release offers even more than I need. It is a bit expensive (like any software of this kind) but honestly it paid for itself in a week or so. We are a large company, but I've noticed that there are considerable discounts for Small Business companies and even educational users, so it's highly recommended to anyone dealing with probability data.
