SMP Not very flashy, but has all the functions you'd expect in a world clock, namely, picking cities and time/date format.
Could use some better UI design though, its not quite up to the standards I've come to expect on OS X. The rotating clock in the Dock is unreadable at any icon size less than huge, and the floating pallette is pretty bland although easy to read (as long as you dont turn transparency on). Just a text printout of city/time in the floating window in a plain box, no analog display or fancy window shapes here.
I don't know if its worth $12, I'll see how it grows on me.
