I'll keep buying Kodax Tmax 100 and 400, at least in the near term. Why? Because I finally nailed down my own film speed and proper +/- development times after a lot of testing this weekend. I hope they keep producing HC110 for a long time too. Not only is it a great developer, but it is good on pancakes, too!
I don't really care much about whether Kodak took down their "how to build a darkroom" web page. There are plenty of sites on the Internet with that kind of information. But these products are readily available to me, and the quality and reliability are, in my mind, excellent.
