Hopefully, things like this contribute to folks becoming more educated about balancing and less intimidated by the balance process. It is all set up to be a very cut-and-dried procedure. IMHO, gearheads who are at a '3rd level' of motor-building, like those who have good tool skills and who have advanced to things like setting valve spring heights, and who are comfortable with doing some basic math, have the level of skills to do a lot of this (if they want to). The rod/piston balance part, and computing the resulting bobweight to which the crank is to be balanced, is one that can be done in a home shop to a very good degree of accuracy, if the tools and procedures and care in work are there.
