It is my experience that just about anything intended for photograp[hic 
use is way overpriced :-=). OK, I can't grind lenses, so I am happy to 
pay for good ones, but I am not going to pay high prices for things I can 
make in an afternoon or so. Quite apart from the fact that making the 
device and experiemnting with it is more fun to me than taking photographs...
