LED Driver recommendation

[scott216]

I'd like to drive 4 RGB LEDs from an Arduino Pro-Mini (5V version) using the PWM output pins.  The LEDs would all be wired together, I don't need to control them individually. The LEDs are common anode drawing 20mA/color, like this one: http://www.sparkfun.com/products/10821/.  I'm looking for suggestions on how to do this.  I guess I could get a little MOSFET for each color and use that with a resistor to drive the LEDs, but I know there are a whole bunch of LED driver chips available.  When when I searched on Digikey I was overwhelmed with the choices and didn't know where to start.  Driver can be through-hole or SMD as long as the SMD can be hand soldered.  I'd appreciate any suggestions.

TLC5925, TLC59281 etc  sounds like good chips to use.

serial in, 16 constant current out...

However serial data in and TS asks for:
