Goldmund and spectral always fall in this catagory, Don't know why? But for some reason still considered in the top of the class... I have no experiance due to very limited resource's on them so I have no clue.
Why do you never near anything about Spectral
Back in the 80's it was considered the creme de la creme. I haven't heard a word about the company in years. Did they go underground or are they just servicing markets outside the U.S. If you know about the companys present day operations I would like to know.
