The primary problem with the cost right now is the small batch size for manufacturing. The cost to manufacture 50 sets of CNCed parts is three times the cost to manufacture 500 sets of CNCed parts. If the demand is only fifty units a year or less, then the cost will probably have to stay high, but if the demand increases, then the cost can come down proportionally.

As far as advantages are concerned, I think that the top flyers stand to benefit the most because the point spread amongst the top flyers is so small, but I also think that the benefits spread to all classes of flyers as well. Based on the way I was scoring about a year aga, I think that I have gained about 50 points flying in the USA Masters class. Although, this is a hard thing to judge, because it assumes that my skills haven't improved, and the skills of others haven't improved either.
