the WS2801 can sink twice as much current, and it supports pwm meaning you can set the brightness of each LED if you wanted more than full on full off operation, but it appears to be in surface mount only so you will either have to make a board (not that hard) or cut some pads in half on a perforated board and solder wires, which is also not that hard, but fiddly.
(29 bucks for 100 aint bad)
or buy that little breakout board they have next to it on the page above
