I seriously doubt Sinar can even afford a field rep anymore. Calumet never was much of a source for it. How much apogeebee still has I don't
know... I picked up some nice compopnents from him at one point. Glennview is also a knowledable. Out here Sinar was once heavily represented in the big SF and Palo Alto photo stores, but there's probably only odds n' ends left now. It's still the mainstay brand of big studios,
esp due to its digi-compatibility.
