@cwhitt - thanks for asking!... Actually, I did end up receiving Papillio as a gift a couple of years ago. I love it, but it hasn't bloomed again since that first year, unfortunately.
I'm not limiting myself to what is in that list, exactly, but those are my favorites that I have found so far. I like reds, doubles, and amaryllis with unique looks. (I'm not really into pinks, generally speaking.)
I have another one to add to the list as of today, both because it is a gorgeous double white, and because it shares my friend's name:
Akiko
White Flower farm carries it, apparently, and I really want it.
Do you have all of your amaryllis listed in your NGA plant list, by chance? I don't have many amaryllis yet, but maybe eventually...
