I've had the Flymount for a few years now - it's a quality piece of kit and will do a variety of angles as it has a ball joint. You can buy it in Australia for $98 if you shop around, compared to $75 for the Masthero (both plus postage), so it's a decision on quality and versatility vs price I guess. A look at the photos of each item online will probably be enough to draw conclusions on comparative quality.
