The musts of a good logo:
Must be memorable
Must work as 1 color
Must be scale able... think big... think bigger! ( Needs to be a VECTOR file)
Must be timeless (A humorous or whimsical logo can only go so far.... think 10-20 years down the road, not current trends)
and most important, it must describe, if the logo doesn't represent the company then it is not effective.
Logos that are superb:
Apple
Nike
McDonalds
Volkswagen
Coca-Cola
They all represent something and they are all timeless and they all have something to remember them by... either by an object or a uniquely made font.
I know that everyone has different tastes and some people like to change their logo from time to time. My suggestion: Do it once and do it right!
