Don,
I don't know anything about this product except for what I just looked up on the internet. It seems that studiomaster went out of business but a company called Phoenix Pro Systems is using the studiomaster manufacturing facilities to build products under the Phoenix Pro name. I guess for this product they wanted to use the Studiomaster name. I did a google search and found this information. The product looks good and the list price is about $400.00 from what I can see, but when I had some studiomaster products some years back, the build quallity always seemed not as pro as many other brands I carried.
