Sundoller, active daylighting

I've seen several ways to actively track the sun and send the light indoors. Sunflower's solution is the simplest of optical design, though I'm not sure why they don't use a full parabolic (I see, it is a 2D reflector, makes sense.) And I really hate these sites that can't tell you what they cost! Call for a quote my ass.. come on, at least order of magnitude.. $1000, $10,000.. Is that too much to ask? Its like an overpriced restaurant, " if you have to ask the price, its too much for you.."
