I am with you. It is my favorite medium-speed color negative film by leaps and bounds.
I will be importing it, myself. As long as it is still manufactured, I will try to get my hands on it. I plan on stocking up on the 120, because I believe it is just a matter of time before it is gone entirely, and there will likely never again be another 100-speed color negative film that I like this much.
There really is no replacement for Reala IME. The closest is Superia 100, but it still isn't as good, and it has been discontinued here as well. S and C (and NC and VC on the Kodak side) fall on either side of it in terms of saturation and contrast, and IME neither are as accurate in color reproduction.
What Reala really strikes me as is a daylight negative film with the qualities you get from T64. Totally accurate, totally plain, not subdued or exaggerated, dead neutral grays and whites that print so beautifully, rich blacks, moderate contrast, very sharp, very fine grained.
EPN and EPP were very close to it, but not only are they both transparency films, but they are both discontinued.
Do not let anyone sell you the idea that Kodak Ektar is a reasonable replacement for it. They are very different films.
I might go for Pro 160S underexposed a stop and pushed if I didn't want to import Reala...but wait...that is gone too!!! So, maybe Kodak 160NC underexposed a stop and pushed a stop?
