Anyone use a Rollmaster timing chain?

Engine builder has recommended a Rollmaster timing chair for my Magnum 360 build. I've never heard of them. Obviously I'm no engine builder but I've flipped through a few summit magazines to know who the popular manufacturers are. Anyone know about these? Good/Bad? I'm building a Magnum 360. Nothing special .30 over street/strip cam EQ heads. I got everything from Hughes. Probably should call them as well. Thanks
