Johnson really made a push with the AFG line just as the specialty fitness dealer market was collapsing. They have tried to make some moves with Sears and online but this looks like it will never be a major brand. The quality is there because it is engineered and built by the same people who make the Vision line but it is a relatively unknown fitness brand. For that reason, you can usually get a good deal on these.
Quality / Philosophy
We visited the headquarters and major factory outside of Shanghai and found that Johnson is the most integrated manufacturer of fitness equipment in the world. This can be both good and bad. The good is that you are in control of almost all aspects of production. The bad is that you are in control of almost all aspects of production- if you mess up there is no one else to blame. They are focused on doing things the right way so it appears that this is a case where it is good overall. We were impressed with their quality procedures and design and testing processes and the reviews will reflect these facts.
Johnson has established themselves as one of the largest and most stable companies in this business and they certainly have their act together so we have confidence in their ongoing product support of all the lines that they produce.
