What's everyone's take on making videos for your band?

The chaps I help out with originally had this down for a home made vid but them bumped into some pro guys:

I've never been much for vids but clearly they can be good fun to come up with and make and can be good for promoting a band.

Ariel Pink is a grand example:

And there's OK Go:

Any experience or examples (good or bad)?
