I would say that any of them would work.  Just read them carefully.  One of the PS on that link was broken.

Also, LED's operate at 20mA or 0.02A.   So a 2 amp power supply will light up 100 LED's.  That is overkill if you ask me.  But it will also give you room to play around with other things if the electronics bug hits you.

The PS I have only supplies 2A.
