It pissed me off that ultracoin is not showing on any coin calculator site(that I know of). Sure you can check your estimated rewards on coin page, but you miss the big picture that way.
So I made my own. Lately the price has gone a bit lower, but most of the time UTC was on top of the list:
http://www.whattomine.com/Block explorer is offline right now so I can only input data manually. Hope this will bring us more people

So, how does your site handle coins at varying N factors? KH/sec isn't simply a matter of dividing by 2 everytime the N increases. Due to the increasing memory requirement, most GPU's need to sacrifice GPU speed for virtual memory (higher lookup gap).
Hey, of course not. I manually track this data. It will get tricky with time, but for now all scrypt-N are on the same boat - correct me if I am wrong.
