I dont have access to any of the privates either but they werent always private and just like they were great sources then, there are great sources now who arent private. Just go with the well knowns, their brands are talked about enough on this board you should know whats what.
Unfortunatly when a source goes private that means his gear is beyond top notch, so your hard pressed to find similar gear available to the public but you can come close.
BS. some private sources have shit gear. or have a few good products and then some are pure shit. It is nice to get gear domestic but no domestic source has better gear then what you can find overseas. I have been around awhile and believe me people are easily pleased!
