if you want cheap leds go to 123leds.com or sickmods.net hes a great guy, and leds come with free resistors, contact him and he should be able to get you the right value.
dont go to dick smiths
sorry its a little off topic but most people like saving money, even if it is a little bit.
Should be able to get the leds shipped with resistors for under $5 opposed to DS's $3 for one led.
