Shutter Speeds (slow/fast)
 

I'm still doing the whole camera evaluation thing and decided to put the Panasonic DVX-100 back in the running after reading about how great the onboard audio is compared to the PD150. What bothers me about the Panny is the limited shutter speeds though.

Is there a real practical need to be able to set the shutter slower than 1/60? I realize this can give you a motion blur effect, but outside of that would you say that not being able to go slower is a major limitation?

Also, if you are not shooting to capture stills, how fast a shutter speed to you need in video? I know in traditional photography, 1/8000 is super fast and can stop an indy car. Some of the current video cameras do 1/10000 and 1/150000. Is this overkill?
What is the fastest shutter speed you ever used and why? (outside of jets, planes, boats, sports, etc.)

Thanks

I can only speak for myself-I use slower shutter speeds more for "special effects" than anything else. During a wedding reception with the right music and right lights going, I'll go to 1/15th or even slower and get an MTV like effect for a few seconds, doing a fire department training video (a burn down) I'll slow down to about the same to give the roaring flames a funky look. I might go to 1/30th under "normal shooting" if it's really bright and I need to open the iris some for DOF control but generally I'm at 1/60th or slightly faster
