Thanks for your feedback, everyone. The Snap On balancers look remarkably similar to the Chinese balancers in which I'm interested. The balance programs that Snap On describes are identical to what the Chinese balancers say they can do.
I'd like to be able to do my own tire changing and road force balancing. I won't be doing a lot of changes and balancing, maybe 12-16 tire balances and changes per year. Ideally, for the balancing, I'd like to do road force balancing. I know the Hunger 9700 is the machine to have but even used...
