dinput event notification

I''m trying to decide how to use mouse input in my dx8 program. Do you think it would be better to use event notification with buffered input as in the scrawl tutorial or could i just have a ProcessMouse() function that gets called each loop to handle buffered input?? What are some ups/downs to each method and which do you recommend? If I use events then should I use a technique similar to the scrawl tutorial with a MsgWaitForMultipleObjects() call in my message loop? This seems like it would waste a lot of time if there was no mouse activity, so I''m leaning towards the other method of checking the buffer each time through my update loop. Any suggestions are welcome! Thanks AZ
