I guess part of the question is, how many loops have you to make from the roll to pay the breaker/spinner?
It's been a long time but I think I paid about $75 for the breaker and another $75 for the spinner. So $150 for the setup, divided by the $3 per loop you pay to have someone else spin your chains. About 50 chains and it's paid for.
But the big savings is not walking into the candy store every couple weeks and buying another $20-$50 worth of stuff whenever you go in to buy chains. I go to the Stihl dealer when I need parts or a new saw, that's it.
