Shift Registry Question

Wow thank you for that link I already bought 50 for 20 usd and it was free shipping but on my next buy (Which i probly will need more) I will buy some from these.
Another question

Do you guys know any places where I can find good schematics examples for the WS2801? I'm not too sure how I should go about wiring I don't want to mess anything up.
I've seen this example and it looks great but What resistors are they using and what other chips are on there? http://learn.adafruit.com/system/assets/assets/000/001/138/original/36mm-io.jpg?1342657099

Yeah I've seen some of maxims stuff its really nice but so expensive D:
