I don't regard them very well personally... I bought a bunch of DAC cables from them, only to have them start emailing me under the guise of assigning me a "account manager"... I blocked their domain from my mail server and told them to never contact me again.
They offer to provide you with personalized service and you block them? What do you do when you walk into a high end watch or clothing store?
FS provides account managers and they are very useful if you are working on a project as they can guide you and help you.
