Webcam recomendations for "Webex" type Video conferencing

Just looking for some recommendations here based upon other user experience.

We have pretty much decided against the higher end Procom type point to point video conferencing solutions for our company. We feel that the cost for such a system would not be appropriate for the usage we have in mind.

Typically, we might do a couple meetings a month between our two offices, and hope to expand into multi-video meetings with clients in the future.

For now, we are just starting at the low end of the tech pool, just to get our feet wet, so-to-speak.

We are looking at a Webex type solution where we could host a meeting, and invite up to 6 video attendees at a time.

So far, I have heard good things about the Logitech series of cameras, such as the Webcam Pro 9000 for around $100.00.

Is this really all that is needed to get a respectable display in a video meeting?

Are there other options I should consider?

For now, we will basically have one camera being used by one person in Wisconsin, connecting to a meeting in Chicago where there will be another camera showing 8  10 attendees of the meeting in a conference room. We may opt to use some type of Web / PC based sound for voice, like a headset for the one guy in Wisconsin, and the cameras microphone for the conference room in Chicago. The other option is just to continue to user Speaker Phone like we do now, and only use Video through the PC/CAM.

Your thoughts would be appreciated.
