Which video conferencing system is the best?

Any recommendations for a good video conferencing system? I have been looking for a system that is easy to use and has good picture quality and isn't too expensive.

This is a website that has various video conferencing systems, such as Polycom, Sony, VCoN, etc. They provide descriptions on each model and features that make it user friendly that do not require technology assistance. Good Luck!

in an office I interned for they also used polycom. It seamed to work pretty well without problems

Thanks for the response it is much appreciated.
