Is JSA a trustworty company
 

I was wanting to know if JSA was a trust worthy authentication company for autos. I mostly have PSA.DNA stuff, but have found some JSA items that I do like. Also what are some other trustworthy companies, and what are the ones to stay far away from?

Thanks Adam

This thread was moved the to the autograph forum (to be discussed there) so it is being locked here. It is probably better to have this discussion in one place. thanks
