The smallest reason is that you ar then able to pull focus, DOF. you cannot do that on lowend consumer cameras.
The biggest reason is the look of the contents of the film, take a DSLR with HD video for example, its razor sharp and it just looks like video, but with DOF. What this system does is that it does the exact same thing but you also get the high acclaimed 35mm film look that you see on the big screen in feature movies. The image has a nice soft and analouge expression, it looks like film - not video.

I need one but same sizes.
google for "garden shops" and chrome steel balls when you get to them, I found no european shops when I bought mine, had to get it from the states. these balls sits on pedistals in gardens in US and make nice reflections of the garden, its a decor item - widely used in the cg industry.
However, you can use practically any non colour graded convex surface, even a big spoon - yes its true, ive seen production sets where they used a big kitchen spoon backside to catch a light map. Use whatever that works is my philosophy, dont get caught up in techgeek land and stall a production just because you dont have access to the newest and best. no production gets finished thinking like that.
