what led driver do you will prefer?
If you can't drive the LED directly from the micro (maybe spend a few cents more for a bright LED and increase the 150 ohm resistor a bit), then just PWM it through a transistor (like your diagram but minus the 0.1uF). 

There's no need for any of the pF capacitors or the 10K to ground in his diagram. His 10K in series is a bit on the high side, your 1K value is better.

Assuming it's just used as an indicator, the 150 ohm value implies either a really crappy cheap LED or a blindingly bright decent LED. Maybe you should ship sunglasses along with it?
