I bought 3 Logitechs for Christmas ... for us and the sets of grandparents. I spent about $75 a piece on them and we all use them with the MSN IM chat feature.
It works pretty well and serves the purpose of allowing the grandparents to see the kids every couple of days since they're all out of state.

Almost $80 on the site, but you can search around for better pricing.
