Rob,
Thanks for your explanation. I recently decided I will go with clear
windows because the tinted ones will mess up the color balance
of photos.
At OSH I spoke with the US manufacturer of the windows and he
said that he can not at this point sell us windows. If Europa does not
survive he will then be able to sell us windows. He was not able to
give me a price.
John, A230
